Highlights of GAO-10-439, a report to congressional requesters. 

Why GAO Did This Study: 

Cost growth and schedule delays are prevalent problems in acquiring 
defense weapon systems. Manufacturing systems has proven difficult, 
particularly as programs transition to production. In December 2008, 
the Department of Defense (DOD) issued an updated version of its 
acquisition policy that reflects earlier consideration of 
manufacturing risks. A joint defense and industry group developed 
manufacturing readiness levels (MRL) to support assessments of 
manufacturing risks. Use of MRLs on all weapon acquisition programs 
has been proposed. In response to a congressional request, this report 
assesses the manufacturing problems faced by DOD, how MRLs can address 
manufacturing problems, how MRLs compare to manufacturing best 
practices of leading commercial firms, and challenges and barriers to 
implementing MRLs at DOD. In conducting our work, we contacted DOD, 
military services, and contractors; held interviews with leading 
commercial firms; reviewed program documents and policy proposals; and 
spoke with manufacturing experts. 

What GAO Found: 

DOD faces problems in manufacturing weapon systems—systems cost far 
more and take much longer to build than estimated. Billions of dollars 
in cost growth occur as programs transition from development to 
production, and unit-cost increases are common after production 
begins. Several factors contribute to these problems including 
inattention to manufacturing during planning and design, poor supplier 
management, and a deficit in manufacturing knowledge among the 
acquisition workforce. Essentially, programs did not identify and 
resolve manufacturing risks early in development, but carried risks 
into production where they emerged as significant problems. 

MRLs have been proposed as new criteria for improving the way DOD 
identifies and manages manufacturing risks and readiness. Introduced 
to the defense community in 2005, MRLs were developed from an 
extensive body of manufacturing knowledge that includes defense, 
industry, and academic sources. An analysis of DOD’s technical reviews 
that assesses how programs are progressing show that MRLs address many 
gaps in core manufacturing-related areas, particularly during the 
early acquisition phases. Several Army and Air Force centers that 
piloted MRLs report these metrics contributed to substantial cost 
benefits on a variety of technologies and major defense acquisition 
programs. 

To develop and manufacture products, the commercial firms we visited 
use a disciplined, gated process that emphasizes manufacturing 
criteria early in development. The practices they employ focus on 
gathering sufficient knowledge about the producibility of their 
products to lower risks, and include stringent manufacturing readiness 
criteria to measure whether the product is sufficiently mature to move 
forward in development. These criteria are similar to DOD’s proposed 
MRLs in that commercial firms: 

* assess producibility at each gate using clearly defined 
manufacturing criteria to gain knowledge about manufacturing early, 

* demonstrate manufacturing processes in a production-relevant 
environment, and, 

* emphasize relationships with critical suppliers. 

However, a key difference is that commercial firms, prior to starting 
production, require their manufacturing processes to be in control—
that is, critical processes are repeatable, sustainable, and 
consistently producing parts within the quality standards. DOD’s 
proposed MRL criteria do not require that processes be in control 
until later. 

Acceptance of MRLs has grown among some industry and DOD components. 
Yet, DOD has been slow to adopt a policy that would require MRLs 
across DOD. Concerns raised by the military services have centered on 
when and how the MRL assessments would be used. While a joint DOD and 
industry group has sought to address concerns and disseminate 
information on benefits, a consensus has not been reached. If adopted, 
DOD will need to address gaps in workforce knowledge, given the 
decrease in the number of staff in the production and manufacturing 
career fields. 

What GAO Recommends: 

GAO recommends that the Secretary of Defense require the use of MRLs 
across DOD programs, strengthen the MRL criteria (process control) for 
production start, assess the need for tools, and assess the 
manufacturing workforce to address knowledge gaps. DOD partially 
concurred with the first recommendation, and concurred with the other 
three.

The Honorable Bill Nelson: 
Chairman: 
Subcommittee on Emerging Threats and Capabilities: 
Committee on Armed Services: 
United States Senate: 

The Honorable Jack Reed: 
United States Senate: 

The Department of Defense (DOD) has a well-documented history of 
taking much longer and spending much more than originally planned to 
develop and acquire its weapons systems. In particular, as systems 
transition from development to production, programs experience 
significant manufacturing problems. While DOD has made some progress 
over the last two decades in addressing the problem--including policy 
changes and advocating the use of best practices for product 
development--GAO's recent weapon system reviews show that 
manufacturing problems, among others, continue to hinder acquisition 
cost, schedule, and performance outcomes. 

It is essential to find better ways of doing business and, in 
particular, to make sure systems are manufactured on time and cost- 
effectively. To this end, leading commercial companies have achieved 
more predictable outcomes from their manufacturing efforts because 
they understand producibility--the relative ease of producing designs 
of an item, product, or system economically with available production 
techniques--and identify manufacturing risks early and manage them 
effectively throughout a product's development life cycle. 

On December 8, 2008, DOD issued a revised version of its policy 
instruction on operation of the defense acquisition system that, among 
other things, recognizes the need to consider manufacturing risks 
earlier in the acquisition life cycle and assesses risks prior to key 
decision points. In response to the need for the department to better 
design and produce more affordable weapon systems, and to give 
decision makers and managers better visibility into their program 
risks, a joint defense and industry working group was established in 
2004 to develop manufacturing readiness levels (MRL), a measurement 
scale designed to improve the management and communication of 
manufacturing risk and readiness throughout acquisitions. Similar to 
technology metrics that measure the readiness of a technology, MRLs 
are new manufacturing criteria that measures the manufacturing 
maturity or readiness of a given technology, manufacturing process, 
system, or element of a weapon system at various phases of the 
acquisition life cycle. 

In response to a request from the Senate Subcommittee on Emerging 
Threats and Capabilities and Senator Reed, we reviewed DOD's efforts 
to adopt MRLs. This report addresses (1) the manufacturing problems 
experienced by selected DOD programs, (2) how MRLs can address DOD's 
manufacturing problems, (3) how proposed MRLs compare to manufacturing 
best practices of leading commercial companies, and (4) the challenges 
and barriers to implementing MRLs at DOD. 

To meet these objectives, we compared the manufacturing practices of 
DOD and its large prime contractors with those of leading commercial 
companies. We performed an aggregate analysis of DOD programs from our 
annual weapons assessment.[Footnote 1] We also evaluated four major 
defense weapon systems in production with known cost and schedule 
problems to gain in-depth insights as to the nature and causes of 
problems. We also evaluated two defense systems known to be producing 
systems within cost and schedule goals and compared their practices to 
those employed by commercial firms. We examined program documentation 
and policy proposals, and held discussions with manufacturing and 
systems-engineering officials from DOD program offices, prime 
contractors, and the Defense Contract Management Agency. We also 
reviewed lessons learned from DOD programs that pilot-tested MRLs. We 
met with officials from the Office of the Secretary of Defense, Air 
Force, Army, and Navy, Missile Defense Agency, Joint Defense 
Manufacturing Technology Panel, Defense Acquisition University, 
National Center for Advanced Technologies, and National Defense 
Industrial Association to discuss manufacturing topics and MRLs. On 
manufacturing workforce issues, we interviewed officials responsible 
for planning activities within each of the military services and the 
Defense Management Contract Agency. We compared manufacturing and 
production considerations in the prior version of DOD's policy 
instruction on operation of the defense acquisition system[Footnote 2] 
to those in the current version of the policy instruction.[Footnote 3] 

To identify manufacturing best practices of leading commercial 
companies, we interviewed and obtained documentation from 
manufacturing, quality, and supplier personnel at five companies, and 
reported on four companies: GE Aviation, an aerospace company; GE 
Healthcare, a producer of healthcare products and services; Honeywell 
Aerospace, a provider of aircraft integrated avionics, engines, 
systems, and services; Siemens Mobility, a producer of light rail 
cars. We selected companies that manufacture complex products and have 
won awards for quality manufacturing. Appendix I includes additional 
details about our scope and methodology. We conducted this performance 
audit from January 2009 to February 2010 in accordance with generally 
accepted government auditing standards. These standards require that 
we plan and perform the audit to obtain sufficient, appropriate 
evidence to provide a reasonable basis for our findings and 
conclusions based on our audit objectives. 

We are making recommendations to the Secretary of Defense to require 
an assessment of the manufacturing readiness across DOD programs using 
MRL criteria, examine strengthening the MRL criteria related to 
process capability and control, assess analytical model needs and 
tools to support MRL assessments, and assess the manufacturing 
workforce knowledge and skills base and develop a plan to address 
DOD's current and future workforce knowledge gaps. In commenting on a 
draft of this report, DOD partially concurred with the first 
recommendation, and concurred with the other recommendations. 

Background: 

In recognition of the lack of manufacturing knowledge at key decision 
points and the need to develop more affordable weapon systems, DOD 
made recent changes to its policy. In 2008, the department made 
constructive changes to its policy instruction on operation of the 
defense acquisition system. It also developed MRLs as a measure that 
could strengthen the way the department manages and develops 
manufacturing-intensive systems. In 2004, the Joint Defense 
Manufacturing Technology Panel[Footnote 4] sponsored a joint defense 
and industry working group to design and develop MRLs for programs 
across DOD. In May 2005, MRLs were first introduced to the defense 
community in DOD's Technology Readiness Assessment Deskbook for 
science and technology and acquisition managers to consider. 

As new manufacturing readiness criteria, MRLs are a measurement scale 
designed to provide a common metric and vocabulary for assessing 
manufacturing maturity and risk. MRL assessments identify the risks 
and manufacturing readiness of a particular technology, manufacturing 
process, weapon system, subsystem, or element of a legacy program at 
key milestones throughout the acquisition life cycle. There are 10 
basic MRLs designed to be roughly congruent with comparable levels of 
technology readiness levels for ease of use and understanding. Table 1 
shows the MRLs and basic definitions (see appendix II for the detailed 
MRL definitions).

The working group also developed a set of elements called "threads" to 
provide acquisition managers and those conducting assessments an 
understanding of the manufacturing risk areas (see table 2). For these 
threads, desired progress is defined for each MRL, to provide an 
understanding of risks as readiness levels increase from one MRL to 
the next. Conceptually, these threads are manufacturing elements that 
are essential to programs as they plan, prepare for, and manage the 
activities necessary to develop a product. For example, the materials 
thread requires an assessment of potential supplier capability by MRL 
3 and an assessment of critical first-tier suppliers by MRL 7. 
Likewise, the manufacturing personnel thread calls for identifying new 
manufacturing skills by MRL 3 and identifying manufacturing workforce 
requirements for the pilot line by MRL 7.

As shown, each basic thread (risk area) has a description and general 
requirements for assessing risks for each thread. The working group 
further decomposed these MRL threads into subthreads to provide users 
a detailed understanding of the various kinds of manufacturing risks. 
See appendix III for a detailed breakdown of these threads (risk 
areas) for each MRL. 

DOD's Long-standing History of Manufacturing Problems: 

GAO has conducted an extensive body of work that highlights many of 
the manufacturing-related problems that both DOD and its prime 
contractors have faced. In many respects, DOD has recognized the 
nature of these problems throughout the years and has taken a number 
of proactive steps to address them. GAO's work has drawn on lessons 
learned and best practices to recommend ways for DOD to improve the 
way it develops and manufactures its weapon systems. Examples from our 
reports include the following: 

* In 1996, GAO reported the practices that world-class commercial 
organizations had adopted to more efficiently produce quality 
products, to improve DOD's quality assurance program.[Footnote 5] DOD 
was spending $1.5 billion extra per year on military-unique quality 
assurance requirements for major acquisitions and billions more on 
cost and schedule overruns to correct problems. GAO concluded that 
repeated unstable designs, poor process controls, and poor transition 
to production caused the manufacturing quality problems. While DOD had 
taken some actions, its culture was cited as the biggest reason for 
slow adoption and unimplemented recommendations. 

* In 1998, GAO reported on best commercial practices to offer ways to 
improve the process DOD uses to manage suppliers engaged in developing 
and producing major weapon systems.[Footnote 6] In assessing defense 
contractors and two case studies of munitions programs, the report 
concluded that suppliers were critical in the amount of technological 
innovation they contribute to the final product. 

* In 2002, GAO reported on how best practices could offer improvements 
to the way DOD develops new weapon systems, primarily the design and 
manufacturing aspects of the acquisition process.[Footnote 7] DOD's 
record showed a history of taking longer and spending more than 
planned to develop and acquire weapon systems, which reduced its 
buying power. The report identified and recommended best practices for 
capturing and using design and manufacturing knowledge early and new 
development processes that included high-level decision points and 
knowledge-based exit criteria before key decisions on production are 
made. Essentially, one of the high-level decision points has become 
what GAO commonly refers to as Knowledge Point 3--the point when a 
program has demonstrated the manufacturing processes are mature. The 
report also recommended a best practice that includes a standard 
called the Process Capability Index (Cpk), a process performance 
measurement that quantifies how closely a product is running to its 
specification limits. The index indicates how well the processes 
statistical performance meets its control limit requirement. 

* In 2008, GAO reported on how DOD and its defense contractors can 
improve the quality of major weapon systems.[Footnote 8] We reported 
that if DOD continued to employ the same acquisition practices as it 
has in the past, the cost of designing and developing its systems 
could continue to exceed estimates by billions of dollars. Quality 
problems were identified as the cause for cost overruns, schedule 
delays, and reduced weapon-system availability. Like DOD prime 
contractors, leading commercial firms rely on many practices related 
to systems engineering, manufacturing, and supplier quality, but they 
were more disciplined, and had institutionalized processes to ensure 
quality. 

* Since 2003, GAO has issued a series of annual assessment reports on 
selected weapons programs, increasing from 77 to 96 programs reviewed. 
[Footnote 9] At $296 billion, the cumulative cost growth for DOD 
programs reported in 2009 was found to be higher than it had been five 
years earlier, and the overall performance of weapon system programs 
was still poor. Although the cost growth and the 22-month average 
delay in delivering initial capabilities was not attributed to 
manufacturing alone, the lack of production maturity was cited as one 
of three key knowledge areas contributing to the department's cost 
growth, schedule delay, and performance problems. 

Revised Policy Incorporates Manufacturing Best Practices: 

DOD's December 2008 revision to its policy instruction on operation of 
the defense acquisition system[Footnote 10] incorporates a number of 
the best practices we identified in our previous work. The instruction 
covers the entire life cycle and considers manufacturing risks earlier 
in the acquisition life-cycle framework. In a November 2003 report on 
DOD's May 2003 revision to its policy, we reported that much of the 
revised policy agrees with GAO's extensive body of work and that of 
successful commercial firms. While we assessed DOD's revised policy as 
providing a good framework for capturing knowledge about critical 
technologies, product design and manufacturing processes, we reported 
in 2006 that acquisition officials were not effectively implementing 
the acquisition policy's knowledge-based process.[Footnote 11] We 
reported that the effective implementation of policy was limited by 
the absence of effective controls that require compliance and specific 
criteria for clearly demonstrating that acceptable levels of knowledge 
about technology, design, and manufacturing have been attained at 
critical junctures before making further investments in a program. We 
concluded that without specific criteria--or standards against which a 
judgment or decision is quantifiably based--decision makers are 
permitted to make decisions on the basis of subjective judgment. The 
December 2008 revised policy instruction establishes target maturity 
criteria for measuring risks associated with manufacturing processes 
at milestone decision points.[Footnote 12] 

During the material solutions phase, prior to milestone A, the 2008 
policy instruction requires the analysis of alternatives to assess 
"manufacturing feasibility." During the technology development phase, 
prior to milestone B, the instruction states the following: 

* Prototype systems or appropriate component-level prototyping shall 
be employed to "evaluate manufacturing processes." 

* A successful preliminary design review will "identify remaining 
design, integration, and manufacturing risks." 

* A program may exit the technology development phase when "the 
technology and manufacturing processes for that program or increment 
have been assessed and demonstrated in a relevant environment" and 
"manufacturing risks have been identified." 

After milestone B, one of the purposes of the engineering and 
manufacturing development phase is to "develop an affordable and 
executable manufacturing process." The instruction says that: "the 
maturity of critical manufacturing processes" is to be described in a 
post-critical design review assessment; system capability and 
manufacturing process demonstration shall show "that system production 
can be supported by demonstrated manufacturing processes;" and the 
system capability and manufacturing process demonstration effort shall 
end, among other things, when "manufacturing processes have been 
effectively demonstrated in a pilot line environment, prior to 
milestone C." 

Finally, at milestone C, the instruction establishes two entrance 
criteria for the production and deployment phase, which include "no 
significant manufacturing risks" and "manufacturing processes [are] 
under control (if Milestone C is full-rate production)." Low-rate 
initial production follows in order to ensure an "adequate and 
efficient manufacturing capability." In order to receive full-rate 
production approval, the following must be shown: 

1. "demonstrated control of the manufacturing process," 

2. "the collection of statistical process control data," and: 

3. "demonstrated control and capability of other critical processes." 

Even with the updated policy instruction in place that includes 
guidance for most knowledge-based practices, inconsistent 
implementation has hindered DOD's past efforts to reform its 
acquisition practices. For example, we reported in 2006 that DOD was 
not effectively implementing the knowledge-based approach process and 
evolutionary approach emphasized in its policy.[Footnote 13] While the 
policy outlined specific knowledge-based process of concept refinement 
and technology development to help ensure a sound business case is 
developed before committing to a new development program, we found 
that almost 80 percent of the programs we reviewed were permitted to 
bypass this process. 

Manufacturing Problems Are Attributed to Several Factors during the 
Planning and Design Phases of Selected DOD Weapons Programs: 

Defense acquisition programs continue to have problems manufacturing 
weapon systems. As a result, systems cost far more and take far longer 
to produce than estimated. Many programs authorized to enter 
production experienced billions of dollars in cost growth after the 
authorization--nearly two-thirds of those programs reported increases 
in average procurement unit costs. Several factors contribute to these 
issues during the planning and design phases. These include the 
inattention to manufacturing during planning and design, poor supplier 
management, and lack of a knowledgeable manufacturing workforce. 
Essentially, some of these programs moved into production without 
considering manufacturing risks earlier in development. This hindered 
managers from later managing those risks until they became 
problematic, and also led to subsequent problems with supplier 
management, such as prime contractors conducting little oversight of 
suppliers. Some programs also had an inadequate workforce--in terms of 
insufficient knowledge and numbers--to effectively manage and oversee 
defense manufacturing efforts. 

Manufacturing Contributed to Growth in Cost and Delays in Schedule: 

Defense acquisition programs continue to be troubled by unstable 
requirements, immature technology, and a lack of manufacturing 
knowledge early in design, resulting in more costly products that take 
longer to produce. Our 2009 annual assessment shows that total 
research and development costs were 42 percent higher than originally 
estimated. These higher costs reflect in part the learning that takes 
place as manufacturing processes are established and used to produce 
the first prototypes. 

Even programs that have been authorized to begin production have 
experienced substantial cost growth after the production decision. 
Production performance can be measured by examining the cost growth as 
expressed in changes to average procurement unit cost. This represents 
the value DOD gets for the procurement dollars invested in a certain 
program and shows the net effect of procurement cost growth and 
quantity changes. Figure 1 shows the levels of average procurement 
unit-cost growth for selected major defense acquisition programs. 
[Footnote 14] 

Figure 1: Distribution of Average Procurement Unit-Cost Growth after a 
Production Decision for Major Defense Acquisition Programs: 

[Refer to PDF for image: pie-chart] 

Programs with less than 5% growth: 39%; 
Programs with 5% to 10% growth: 29%; 
Programs with 11% to 15% growth: 16%; 
Programs with more than 15% growth: 10%;

Note: Data include all major defense acquisition programs that entered 
production in fiscal year 2000 or later. 

[End of figure] 

As indicated in figure 1, nearly two-thirds of programs that entered 
production after 2000 reported more than a 5 percent increase in 
average unit cost growth, while 32 percent of programs reported 
average unit cost growth that ranged from 11 percent to more than 15 
percent. One program reported a 25 percent increase in average 
procurement unit cost. Further, 42 percent of those programs 
experienced production cost increases when procured quantities 
decreased or remained the same. For example, the Black Hawk 
helicopter's 2007 production estimate had no increase in quantities 
since 2005, yet its production cost increased $2.3 billion, and 
average procurement unit cost rose by 13 percent. The Joint Air-to-
Surface Standoff Missile had an 8 percent quantity decrease since the 
2004 production decision; but the production costs increased by $561 
million and average procurement unit cost increased by 25 percent. 

As for schedule growth, DOD has continued to experience delays in 
delivering new or modified weapon systems to the warfighter. Over 50 
percent of current programs in production have encountered some form 
of delay after the production decision, when manufacturing processes 
should be in control. Consequently, warfighters often must operate 
costly legacy systems longer than expected, find alternatives to fill 
capability gaps, or go without the capability altogether. 

The four DOD weapon systems we selected for in-depth review with known 
cost, schedule, and performance problems reported several key factors 
that contributed to manufacturing problems. These include the 
inattention to manufacturing during planning and design, poor planning 
for supplier management, and lack of a knowledgeable manufacturing 
workforce. Capturing critical manufacturing knowledge during the 
planning and design phases before entering production helps to ensure 
that a weapon system will work as intended and can be manufactured 
efficiently to meet cost, schedule, and quality targets. The programs 
in our review often lacked manufacturing knowledge at key decision 
points, which led to cost growth and schedule delays. For example, the 
Joint Air-to-Surface Standoff Missile program--an autonomous, air-to- 
ground missile designed to destroy high-value targets--experienced a 
critical unit-cost breach due to missile reliability problems not 
being addressed early in the design phase.[Footnote 15] Also, the 
Electromagnetic Aircraft Launch System--a new catapult technology 
being developed for the Navy's newest class of aircraft carriers--had 
experienced problems manufacturing compatible materials, which 
resulted in cost growth and schedule delays and was the focus of 
recent congressional interest. Figure 2 summarizes contributing 
factors for manufacturing problems experienced by the four DOD weapon 
systems.

As indicated, most of the programs had more than one major problem 
related to manufacturing. These issues illustrate the major problems 
we discussed with defense and contractor officials, but do not 
encompass all the manufacturing problems experienced by the programs. 
For example, a recent Air Force study reports that manufacturing and 
quality assurance requirements are not included in the contracts to 
develop weapon systems, which could affect the contractor's approach 
to manufacturing. Officials from the Defense Contract Management 
Agency--a DOD component that works directly with defense suppliers to 
ensure that supplies and services are delivered on time, at projected 
cost, and meet performance requirements--also reported similar 
contract issues that could affect contractor performance on 
manufacturing. 

Manufacturing Was Overlooked during Early Development: 

Each of the four programs we examined did not give manufacturing 
strong consideration during the early planning and design phases. 
Programs were moved into production largely without considering 
manufacturing risks earlier in the acquisition process, as 
demonstrated by the experiences of the Exoatmospheric Kill Vehicle and 
the H-1 helicopter upgrade program. The Exoatmospheric Kill Vehicle 
was designed to intercept and destroy high-speed ballistic missile 
warheads in mid-flight, while the H-1 upgrade program converts the 
attack helicopter and the utility helicopter to the AH-1Z and UH-1Y 
configurations, respectively. 

The Exoatmospheric Kill Vehicle program was put on an accelerated 
development schedule in response to a directive to develop and deploy, 
at the earliest possible date, ballistic missile defense drawing on 
the best technologies available. According to the contractor, it 
bypassed some of its normal development-review processes to accelerate 
delivery of the vehicle, which also resulted in a high acceptance of 
manufacturing risks without sufficient identification and management 
of risk-mitigation plans. For example, the program went into 
production without completing qualification testing. In addition, the 
contractor continued to incorporate design changes while supplier 
production was ongoing, resulting in rework and disruption to the 
production line. Early lots of kill vehicles were built manually by 
engineers in the absence of automated production processes, which 
caused dissimilarities among vehicles in the fleet and will make 
refurbishments difficult.[Footnote 16] 

For several reasons, the H-1 helicopter upgrade program did not 
include manufacturing in the early phases of planning and also 
proceeded to production before its design was mature, according to the 
contractor. First, the program underestimated the complexity of 
updating and remanufacturing the aircraft without historical drawings. 
The emphasis was placed on minimizing development costs and resources 
were not available to assess manufacturing challenges early in the 
redesign process. Furthermore, the program started low-rate production 
before completing operational evaluation testing. As a result, the 
problems uncovered during testing had to be corrected on aircraft that 
were on the assembly line. Also, constant change orders and factory 
bottlenecks, among other problems, affected program costs and 
schedules. The schedule pressure allowed little opportunity to remedy 
the manufacturing problems, resulting in more complicated and 
expensive fixes. Ultimately the schedule slowed and the costs 
increased to the point that the program abandoned the remanufacturing 
upgrade and, instead, opted to purchase newly manufactured aircraft 
cabins for the UH-1Y configuration. 

Poor Planning Led to Supplier Problems: 

Inattention to manufacturing during planning and design led to 
subsequent problems with supplier management in two major defense 
acquisition programs we reviewed. Specifically, the prime contractors 
did not give adequate attention to managing their suppliers. For 
example, program officials for the Joint Air-to-Surface Standoff 
Missile told us that the responsibility for manufacturing processes 
and discipline shifted in the 1990s from the government to the defense 
contractors. The government started to rely on the prime contractor to 
ensure quality and reliability, particularly with subtier suppliers. 
In this case, the program office told us that the prime contractor for 
the missile program relied on the subtier suppliers to self-report 
their capabilities and did not engage in effective oversight of their 
work, which led to defective parts. The program office recently 
recruited experts in manufacturing to help the prime contractor 
address their supplier problems more effectively. 

In the Exoatmospheric Kill Vehicle program, supplier quality was 
inconsistent, resulting in unnecessary rework and uncovering problems 
late in production. For many suppliers, the kill vehicle program 
represents a small portion of their business, so the emphasis on 
quality was often lacking. Further, the program was initially procured 
as a capability based program, rather than requirements based program. 
Thus, the prime contractor did not impose requirements on the 
subcontractors to comply with stringent requirements for space 
programs. In turn, the subcontractors did not implement sufficient 
requirements which led to recurring quality issues. 

Lack of Manufacturing Knowledge Contributed to Problems: 

Some DOD programs and prime contractors had an inadequate defense 
manufacturing workforce--both in terms of numbers and experience--to 
effectively manage and oversee manufacturing efforts, which resulted 
in schedule delays or cost inefficiencies. The manufacturing workforce 
includes occupations such as specialists in quality assurance, 
business, manufacturing engineering, industrial engineering, and 
production control. In many cases, the programs lacked manufacturing 
expertise early in development, which hindered the program's ability 
to later manage manufacturing risks. For example, the contractor for 
the Electromagnetic Air Launch System did not have sufficient systems- 
engineering personnel involved in the design to help it transition 
from development to production. As a result, the program encountered 
schedule delays and cost increases. DOD conducted a program assessment 
review, which led the program office and contractor to increase 
systems engineering staff. 

For the Exoatmospheric Kill Vehicle program, the contractor's 
workforce and manufacturing processes could not readily undertake the 
rigors of production for a space-based capability, part of which must 
be manufactured in a clean room environment, and all of which commands 
rigorous processes and procedures due to highly technical designs. The 
contractor's hourly assembly personnel were trained to build tactical 
missiles on a high-rate production line and were not sufficiently 
trained in the quality-control standards required by clean-room 
manufacturing, such as carefully controlling foreign-object debris, 
specially maintaining the clean room, and using a partner in certain 
high-level tasks to ensure all steps are properly followed. These 
standards were not institutionalized, and the contractor eventually 
had to modify its facilities and production standards to correct the 
manufacturing problems. The facility had to be retooled and 
reconfigured late in development. The contractor also experienced high 
turnover in its workforce due to the increasing demands associated 
with working in a clean-room environment and working long hours. 

MRLs Have Been Proposed to Improve the Way DOD Identifies and Manages 
Manufacturing Risk and Readiness: 

The Joint Defense Manufacturing Technology Panel working group has 
proposed MRLs as new manufacturing readiness criteria that could 
improve weapon system outcomes by standardizing the way programs 
identify and manage manufacturing risks associated with developing and 
fielding advanced weapon systems. MRLs were first introduced to the 
defense community in DOD's 2005 Technology Readiness Assessment 
Deskbook as an important activity for science and technology and 
acquisition managers to consider. An analysis by the working group 
shows that MRLs address many of the manufacturing issues not covered 
by DOD's technical reviews, particularly reviews conducted in the 
early phases of acquisition. In their development, comprehensive 
efforts were undertaken to design and develop MRLs from DOD as well as 
industry resources. For example, the working group formulated MRLs 
from a manufacturing knowledge base of defense, industry, and academia 
to address two key areas of risk--immature product technologies and 
immature manufacturing capability. The working group also designed 
MRLs as a structured and disciplined approach for the way 
manufacturing risk and readiness is expected to be identified and 
assessed. The working group also developed a set of tools that include 
a deskbook, checklist, and a website to help managers and users apply 
MRLs and conduct assessments. In addition, the Army and Air Force 
report that their use of MRLs on pilot programs contributed to 
substantial cost benefits on a variety of programs, including major 
acquisition programs. 

MRLs Were Developed from Knowledge-Based Resources on Manufacturing: 

To develop MRLs, the working group conducted comprehensive sessions 
with industry participants to ensure the metrics and vocabulary for 
assessing manufacturing readiness would be an all-inclusive body of 
knowledge. Officials stated that a mature set of manufacturing 
knowledge resources already existed but it was scattered and not 
consistently applied in a disciplined way that aligned with the DOD 
acquisition life-cycle framework. In their formulation, MRLs were 
developed from an extensive body of manufacturing knowledge that 
included, but was not limited to, the following defense, industry, and 
academic sources: 

* DOD Instruction 5000.02, Operation of the Defense Acquisition System 
(Dec. 8, 2008), 

* Navy best-practices manual for using templates on design and 
manufacturing best practices, 

* Air Force manufacturing development guide, 

* military standards and specifications, and: 

* Malcolm Baldrige quality award criteria. 

Other standards and technical sources were obtained from the Institute 
of Electrical and Electronics Engineers, the International Standards 
Organization on quality management systems, automotive industry 
quality standards, and the supplier model from the Massachusetts 
Institute of Technology. 

Analysis Shows MRLs Address Manufacturing Gaps in DOD's Technical 
Reviews: 

An analysis conducted by the working group shows that MRLs address 
many of the manufacturing gaps identified in several of DOD's 
technical reviews[Footnote 17] that provide program oversight and 
determine how well programs are meeting expected goals, particularly 
the reviews conducted in the early acquisition phases. According to 
the working group, addressing these manufacturing gaps is fundamental 
to improving the way programs plan, design, and prepare for 
manufacturing. For example, the working group's analysis shows that 
DOD's current systems-engineering technical review checklist used for 
preliminary design reviews[Footnote 18] has only 27 of 759 total 
questions that deal with core manufacturing-related questions, whereas 
the MRL 6 assessment checklist for this juncture has 169 core 
manufacturing questions. More importantly, the technical review 
checklist did not address key manufacturing discipline in the areas of 
program management, systems engineering, requirements management, risk 
management, and program schedule. Similarly, the technical review 
checklist used for critical design reviews[Footnote 19] has only 22 of 
824 total questions that deal with core manufacturing questions, 
whereas the MRL 7 assessment checklist for this juncture has 162 core 
questions. Core manufacturing disciplines were not addressed in the 
specific areas of management metrics, manufacturing planning, 
requirements management, system verification, and other areas. 
Finally, DOD's technical review checklist used for production 
readiness reviews[Footnote 20] has 194 of 613 total questions that 
deal with core manufacturing questions. While the MRL 8 assessment 
checklist has 14 fewer core questions on manufacturing at this 
juncture, the working group stated these core manufacturing questions 
are addressed earlier in the acquisition framework, which is 
reflective of commercial best practices where such manufacturing 
topics and discipline are addressed, in contrast to DOD's current 
practice. 

Draft Deskbook Explains MRL Application and Assessments: 

The draft MRL deskbook is a detailed instructional resource on how to 
apply MRLs and conduct assessments of manufacturing risk and 
readiness, such as how to structure and apply evaluations to a 
technology, component, manufacturing process, weapon system, or 
subsystem using the MRL definitions. It also demonstrates how 
assessments should be carried out at various phases by the managers of 
science and technology projects and technology demonstration projects 
intending to transition directly to the acquisition community, as well 
as acquisition program managers and the people involved in conducting 
assessments. According to the working group, MRLs can not only be used 
to improve how DOD manages and communicates manufacturing risk and 
readiness, but can also give decision makers and manager's better 
visibility into program risks. For example, a variety of manufacturing 
status and risk evaluations have been performed for years as part of 
defense acquisition programs in a variety of forms--for example, 
production readiness reviews, manufacturing management/production 
capability reviews, etc. However, these structured and managed reviews 
do not use a uniform metric to measure and communicate manufacturing 
risk and readiness. 

MRLs, when used in combination with technology readiness levels, are 
expected to address two key risk areas--immature product technologies 
and immature manufacturing capability. The draft deskbook says that it 
is common for manufacturing readiness to be paced by technology 
readiness or design stability, and that it is not until the product 
technology and product design are stable that manufacturing processes 
will be able to mature. MRLs can also be used to define manufacturing 
readiness and risk at the system or subsystem level. For these 
reasons, the MRL definitions were designed to include a target level 
of technology readiness as a prerequisite for each level of 
manufacturing readiness. Figure 3 shows the relationship of MRLs to 
system milestones and technology readiness levels in the defense 
acquisition life-cycle framework.

MRL Assessments Provide Basis for Identifying, Planning, and Managing 
Program Risks: 

MRL assessments are intended to leverage better manufacturing 
knowledge, enabling managers to be aware of problems or risks early in 
development, when they are easier to resolve and before significant 
investments are made. In turn, these risks can be addressed earlier in 
the life cycle when costs are lower. For example, the ability to 
transition technology smoothly and efficiently from the laboratories, 
onto the factory floor, and into the field is a critical enabler for 
evolutionary acquisition. 

Assessments can be applied to a technology, manufacturing process, 
weapon system, or subsystem using the definitions as a standard. As 
part of the assessment, a comparison is made between the actual MRLs 
and the target MRL levels. The difference between the two identifies 
the risks and forms the basis for assisting managers to develop a plan-
-called a manufacturing maturation plan--to remove or reduce them. 
Risks should be identified throughout the life cycle and, when targets 
are not met, the plan updated to ensure the appropriate MRL will be 
achieved at the next decision point. The manufacturing maturation plan 
identifies manufacturing risks and provides a plan for mitigating each 
risk area throughout the duration of the technology or product- 
development program. The draft MRL deskbook says every assessment of 
manufacturing readiness should have an associated plan for areas where 
the MRL has not achieved its target level. The deskbook requires a 
manufacturing maturation plan to include the most essential items in 
planning for the maturity of an element of assessment that is below 
its target MRL. These include a statement of the problem that 
describes areas where manufacturing readiness falls short of the 
target MRLs, including key factors and driving issues, solution 
options and consequences of each option, and a maturation plan with a 
schedule and funding breakout. Other information should include the 
status of funding to execute the manufacturing plan and specific 
actions to be taken and by whom, and the MRL to be achieved and when 
it will be achieved. 

MRL Pilot Programs Show Positive Benefits: 

Army and Air Force programs have pilot-tested MRLs on science and 
technology and some major acquisition programs in an effort to 
increase the manufacturing readiness and maturity to higher levels 
appropriate to the phase of development. Both services performed MRL 
assessments on selected pilot programs to address manufacturing risks 
and assess technology transition. The Army reports numerous benefits 
from the use of MRLs such as manufacturing efficiencies, improved 
labor utilization, and cost benefits. Similarly, the Air Force has 
used MRLs to manage its manufacturing risks associated with new 
technologies, yielding tangible benefits. While MRLs cannot take full 
credit for all benefits derived in the pilot programs, officials noted 
they are a good way to manage, mitigate, and communicate--between 
science and technology, acquisition, the user, and the system 
developer--readiness and risks early and throughout the acquisition 
process to avoid major consequences from manufacturing-related 
problems. These programs provide insight on how the acquisition 
community can utilize MRLs within weapon system programs. 

Army: 

In 2004, the Army's Aviation and Missile Research, Development and 
Engineering Center began applying MRLs to various technologies in 
concept development, including those technologies transitioning to 
engineering and manufacturing development. Officials stated that 
without cost and manufacturing readiness planning, science and 
technology programs face certain barriers to transition, resulting in: 
(1) high unit production cost caused by a focus on technology without 
regard to affordability; and (2) manufacturing problems caused by 
design complexity resulting in a technology that is not feasible to 
manufacture. For example, the Army has applied MRLs to many programs, 
including warfighter-protection materials, Micro-Electro-Mechanical 
Systems, embedded sensors, and helicopter cabin structures. The 
warfighter-protection program--the next generation of helmets and body 
gear--reported that it was able to reduce scrap by 60 percent and 
reduced touch labor by 20 to 40 percent. On programs where cost 
benefits could be roughly calculated, the Army believes that MRLs, 
among other improvement initiatives, contributed to the $426 million 
in benefits on seven programs. MRLs were also used as a metric in the 
Technology Transition Agreement to communicate manufacturing maturity 
and facilitate a smooth transition to the acquisition community. 

Air Force: 

Air Force officials we met with discussed using MRLs to assess and 
identify gaps and understand risks in manufacturing maturity that 
would delay technology transition into an advanced systems development 
program or a fielded system upgrade. The Air Force has conducted 
several MRL assessments on advanced technology demonstrations and 
major defense acquisition programs, including the MQ-9 Reaper Unmanned 
Aircraft, Joint Strike Fighter, Advance Medium-Range Air-to-Air 
Missile, X-band thin radar array, and Sensor Hardening for Tactical 
Systems. Officials reported that the use of MRLs have contributed 
millions of dollars in cost avoidance, increased production rates, and 
has accelerated technology transition. For example, the Air Force 
reported realizing $65 million in savings by addressing problems with 
a costly manual drilling process. MRLs were used to raise new drilling 
technology from MRL 4 to MRL 9, achieving a unit-cost savings of 
$17,000 per aircraft from reduced tooling, manpower, floor space 
usage, and time. 

Because of MRL assessment's success on advanced technology programs, 
the Assistant Secretary of the Air Force for Acquisition directed the 
program office to perform MRL assessments on key MQ-9 Reaper 
manufacturing processes and technologies. The MQ-9 Reaper is an 
unmanned aerial vehicle designed to provide a ground attack capability 
during reconnaissance and surveillance missions. Officials stated that 
the MRL assessment results have (1) identified five areas that needed 
review prior to a milestone C production decision; (2) identified two 
risks to full-rate production--mitigations are in progress; and (3) 
provided evidence to support the contractor's ability to meet the 
production goal of two aircraft per month. To ensure that 
manufacturing requirements are enforced, officials have developed 
policy for programs managers to assess manufacturing readiness at key 
decision points. To support that policy, the Air Force has developed 
training for integrated product teams to execute the manufacturing 
readiness assessments. Also in August 2009, the Air Force Institute of 
Technology established a Manufacturing Readiness Assessment course to 
provide training for the assessments within the Air Force and is 
currently open to all services and industry. 

DOD's Proposed MRLs Embody Many Best Practices of Leading Commercial 
Firms: 

To successfully develop and manufacture their products, the commercial 
firms we visited used a disciplined, gated process that emphasized 
manufacturing criteria early and throughout the product's development. 
To measure manufacturing maturity, these firms developed processes 
that give manufacturing readiness and producibility primary importance 
throughout the product-development process, focusing on producing a 
product, not developing a technology. The goal is business 
profitability, and manufacturing maturity is important to this process 
from the earliest stages. 

The best practices they employed were focused on gathering a 
sufficient amount of knowledge about their products' producibility in 
order to lower manufacturing risks and included stringent 
manufacturing readiness criteria--to measure whether the product was 
mature enough to move forward in its development. In most respects, 
these criteria are similar to DOD's proposed MRLs. For example, as 
with MRLs, commercial firms: 

* assess producibility at each gate using clearly defined 
manufacturing readiness criteria, 

* gain knowledge about manufacturing early, 

* demonstrate manufacturing processes in a production-relevant 
environment, and: 

* emphasize the importance of effective supply-chain management. 

Essentially, commercial firms emphasize these criteria in order to 
maximize their understanding of manufacturing issues, to mitigate 
manufacturing risks that could affect business profitability or 
schedule goals for getting the product to market. DOD's MRLs were 
designed to mitigate similar manufacturing risks. However, the 
difference is that the commercial firms we visited required that their 
manufacturing processes be in control prior to low-rate production, 
whereas DOD's proposed MRL criteria do not require as early control of 
the manufacturing process. 

DOD's MRLs Are Similar to Manufacturing Criteria Used by Leading Firms: 

Leading commercial firms use manufacturing readiness criteria, similar 
to DOD's MRLs, to assess the producibility of a system, gathering 
knowledge about the producibility of a product and the maturity of the 
manufacturing process. These criteria are applied early, even before a 
product formally enters into development, to identify and manage 
manufacturing risks and gaps. Additional manufacturing readiness 
criteria are applied through all the stages of a product's development 
and production until the product is ready for commercial release. The 
firms we visited used manufacturing readiness criteria to measure both 
the readiness of the product or material to enter into development and 
to proceed through the necessary gates. Table 3 below shows examples 
of manufacturing readiness criteria that are common to both the MRLs 
and the commercial criteria, to illustrate their similarities. Both 
emphasized identifying risks and developing plans to mitigate these 
risks, setting realistic cost goals, and proving out manufacturing 
processes, material, and products. 

Table 3: Many Manufacturing Criteria Used by Leading Commercial Firms 
Are Similar to DOD's MRLs: 

MRL/phases: MRL 1-3; Pre-Concept Development (Invention Stage); 
Commercial manufacturing criteria and DOD MRLs: 
* Relevant materials and processes evaluated for manufacturability; 
* Cost models developed for new processes; 
* Critical manufacturing processes identified. 

MRL/phases: MRL 4; Concept Development; 
Commercial manufacturing criteria and DOD MRLs: 
* Risk-mitigation plans in place for management of manufacturing risks; 
* Key materials issues identified; 
* Manufacturing strategy developed and integrated with acquisition 
strategy. 

MRL/phases: MRL 5-6; Technology Development; 
Commercial manufacturing criteria and DOD MRLs: 
* Basic design requirements defined and all critical technology and 
components tested and evaluated; 
* Critical suppliers identified/supply chain in place; 
* Realistic cost targets are set; 
* Manufacturing processes and materials demonstrated in a production-
relevant environment. 

MRL/phases: MRL 7; Product Development; 
Commercial manufacturing criteria and DOD MRLs: 
* Product requirements and features well-defined; 
* Pilot lines' yield-data gathered and assessed;

environment.

Best Practice: Commercial Companies Emphasize Manufacturing Criteria 
Early and at Every Stage of the Product-Development Life Cycle: 

Each commercial firm we visited developed a disciplined framework for 
product development that assessed producibility at each gate using 
clearly defined manufacturing-maturity criteria that are similar in 
many respects to DOD's MRLs. These include assessments of all aspects 
of manufacturing technology and risk, supply-chain issues, production 
facilities and tooling, and materials. Throughout the product- 
development life cycle, these criteria were applied to determine entry 
or exit into the next phase and led to informed decisions about 
whether the product was ready to move forward in its development. 
Manufacturing risks--such as those found in new manufacturing 
technologies or production facilities, new or revolutionary materials 
or supply-chain issues--were assessed at each step. Deliverables, 
including risk-identification and mitigation plans, manufacturing 
plans, and funding and resource needs, were required at each gate in 
order to progress to the next product-development gate. Targets were 
developed for each gate, including cost, schedule, and yield goals, 
and the product team was responsible for either meeting these targets 
or having risk-mitigation plans in place if the targets had not been 
met. 

GE Aviation exemplifies this disciplined process, using a highly 
structured gated process with detailed checklists for entry and exit 
into each phase. Like DOD's MRLs, these checklists contain 
increasingly detailed criteria--as they move from product start to 
production--for evaluating manufacturing technologies, cost drivers, 
materials, and supply-chain issues. Structured teams are brought 
together, tools are identified for execution and control of the 
process, and scheduled reviews are conducted with defined deliverables 
and checklists for each milestone. At each milestone, a vigorous 
review of the plans for the product's development and manufacturing 
and risk-reduction efforts highlights issues before they become 
problems. The firm's goal is to have mature processes by production. 
To achieve this, it considers manufacturing readiness throughout. Each 
project's team is cross-functional and includes senior management, mid-
management and the project team. This robust review process leverages 
expertise across GE Aviation, reduces risk, and highlights issues 
before they become problems. 

As with all the commercial firms we visited, GE Aviation requires 
strong management involvement at each gate, along with decision 
reviews to determine if enough knowledge is available and risk-
mitigation plans are in place to proceed or if actions to address and 
mitigate manufacturing risks can show a viable way forward. This 
allows management to resolve problems rather than pass them on to the 
next phase. At project start, which corresponds to MRL 4, the senior 
leadership team and product leadership team generate the product idea 
and assess the need for the project. They provide linkage between the 
business strategy and the project and develop the high-level project 
strategy. They identify any new product material or manufacturing 
processes and begin to develop a risk-reduction strategy for these 
issues. By the time the product enters the preliminary design phase, 
senior leadership and project teams agree on the approach to the 
project. At this time, product directors must have a manufacturing 
plan in place in order to identify how they are going to achieve 
manufacturing readiness. Technical risks are identified in the 
manufacturing plan, as well as risk-abatement strategies for materials 
and manufacturing processes and supply-chain risks. The plan has to 
show how issues will be successfully addressed by the detailed design 
phase, when leadership, the project team, and customers agree on the 
product to be delivered. If agreement is reached, they freeze the 
project plan and a decision is made to fund or terminate the project. 

Multidisciplinary Team/Manufacturing Experts: 

In the commercial firms we visited, product-development teams were 
multidisciplinary, generally including management, manufacturing, 
quality, finance, suppliers, and engineering, with necessary skills 
available to assess manufacturing readiness. Leading firms recognize 
the value of having a knowledgeable, well-trained, and skilled 
manufacturing engineering workforce involved in these 
multidisciplinary teams from the beginning and throughout the process. 
When Honeywell reorganized its aerospace business in 2005, it created 
an advanced manufacturing engineering organization to focus on 
manufacturing concerns in the earliest phases of new product- 
development programs. This organization consists of engineers to 
support various manufacturing disciplines in Honeywell. An important 
part of this advanced engineering organization is its technology 
group, which consists of a select number of technology fellows with 
extensive expertise in key manufacturing disciplines that touch nearly 
all the products Honeywell produces. Honeywell retains highly skilled 
manufacturing expertise through this program and uses these 
experienced and knowledgeable manufacturing engineers to oversee each 
project's manufacturing assessments. 

Maturing Technology and Manufacturing Processes: 

Commercial firms focus on maturing and validating technology and 
manufacturing processes before these are associated with a product and 
before entry into the gated process. They keep invention and unproven 
technologies in the technology base until their producibility at the 
scale needed can be proven. As an example, GE Healthcare's Gemstone 
scintillator underwent years of laboratory development on a small 
scale until GE Healthcare was satisfied that this material was ready 
to be used on its computed tomography (CT) scanners. Scintillators 
work by converting the X-rays in the CT scanner into visible light. GE 
Healthcare had been manufacturing its own scintillators since the late 
1980s, but it needed an improved one that worked faster, for better 
clarity of vision and to reduce the amount of exposure to radiation. 
In 2001, the firm began basic composition development at the 
laboratory scale and narrowed down the alternatives to find the 
material with the best properties for this use. Even at this early 
stage, several years before the material would enter into GE 
Healthcare's gated process, there was early engagement by the chemists 
with the manufacturing side. Before they decided on a solution, a 
determination was made that it could produce them with sufficient 
yield and quality: even if a material had the best optical qualities, 
it had to balance this with its producibility. GE Healthcare tested 
thousands of alternatives to determine what could meet its technical 
requirements and be producible in the quantities needed. The firm 
narrowed it down to a garnet-based, rare-earth minerals composite, and 
began producing it in small but increasing quantities. After narrowing 
the field to this garnet-based compound, GE Healthcare began to 
determine its suppliers and what equipment was needed. The firm then 
began building its first pilot plant to produce the material and the 
scintillators, 2 years before the scintillator entered the firm's 
gated process. Figure 4 shows a photo of a CT scanner that uses the 
scintillator technology.

Best Practice: Commercial Firms Have Adopted DOD's MRLs or Are 
Employing Similar Criteria in Their Product-Development Process: 

Because leading commercial firms focus on producibility as a key 
element to successfully develop products, they use rigorous analysis 
methods to assess producibility and to identify and manage 
manufacturing risks and gaps. They apply these methods and tools early 
and throughout product development and use them to manage their 
product development on a daily basis. This commercial approach is a 
process in which quality is designed into a product and manufacturing 
processes are brought into statistical control to reduce defects, in 
contrast to practices employed by many defense contractors where 
problems are identified and corrected after a product is produced. 

Some firms were familiar with the DOD MRL proposal and had taken steps 
to use the concepts at their own companies. Honeywell, for example, 
determined that early decisions were responsible for many production 
issues and so they developed analytical tools and models that support 
evaluations of manufacturing and risk throughout the product- 
development life cycle. In 2005, Honeywell engineers began looking for 
a way to measure manufacturing readiness and producibility, since they 
realized that early program decisions were driving many production 
issues and that by the time a product entered engineering and 
manufacturing development, it was too late to efficiently affect these 
issues. Some of these issues include cost overruns, quality problems, 
low-yield issues, service and maintainability inefficiencies, and 
supply-chain problems. 

A literature search led them to DOD's MRLs and they realized that 
these could provide the type of metric needed for a quantitative 
assessment. Honeywell then evolved its own criteria from these MRLs, 
modified to meet Honeywell's needs and expanded to address concerns 
such as design, obsolescence, and testability issues. Their MRL 
Maturity Model assessment tool, which evolved from an early version of 
DOD's MRLs, is the main tool in the assessment and is built upon three 
enabling producibility analysis tools. The model provides an MRL score 
for the product "as is," which is then compared to the MRL score 
desired to exit the phase. This model gives the firm a systematic way 
to be sure all the information is considered and the right questions 
are asked by less-experienced engineers who support the program. This 
MRL tool was developed 5 years ago and has evolved in an iterative, 
continuous improvement process since then, based on feedback from its 
users. Figure 5 shows a simplified depiction of this MRL model and the 
three enabling tools. 

Figure 5: Honeywell Uses Three Producibility Models and MRL Workshop: 

[Refer to PDF for image: illustration] 

Manufacturing Complexity Model:

to gain consensus on ratings for each category. 

The above combine to yield:

workshop to evaluate manufacturing maturity and identify gaps. 

MRL Maturity Model Output:

[End of figure] 

The output of this tool is an MRL assessment score that can identify 
gaps or risks. For example, spreadsheets show the MRL scoring at a 
glance for each of the elements evaluated, pinpointing the gaps; risk 
worksheets to quantify the risks; and action plans to close the gaps 
and mitigate these risks. It links to the firm's gated process, 
providing entry and exit criteria and feedback on how to meet these 
criteria. The important information obtained is not necessarily what 
MRL level the item is at currently, but rather the robustness of the 
gap-closure plan to get to the desired level for the next gate. The 
application of the MRL tool helps identify what these key gaps are and 
what steps are required to close them. 

The three enabling producibility tools that provide support for this 
assessment and early input on the producibility risks are: a Design 
for Manufacturing Model, a Product Complexity Model and a Yield 
Prediction Model: 

* Manufacturing Complexity Model: This model identifies the design 
features that are driving manufacturing complexity into the design and 
enables scenarios to be evaluated to see what actions can be taken to 
simplify the design. Higher-complexity designs generally cost more and 
are higher risk, so the goal is to identify alternative design 
solutions that minimize complexity, but still meet all the performance 
requirements. 

* Yield Prediction Model: Honeywell has also developed yield 
prediction models based on statistical principles that correlate 
opportunities for defects in a design to established process 
capability benchmarks. This approach is used to predict yield during 
early design activities based on knowledge of the manufacturing 
processes used and the complexity of the design. 

* Design for Manufacturing Scorecard analysis: The third Honeywell- 
developed tool is a design for manufacturing scorecard, which 
quantifies how well the design adheres to recommended best practices. 
The goal of using the tool is to provide feedback to the designers so 
that they see how their design decisions directly affect producibility 
and help pinpoint improvement areas early in the process. 

Honeywell then conducts an MRL workshop, with a team led by an 
engineer from its Advanced Manufacturing Engineering group that 
includes the program manager and various subject-matter experts. This 
team reviews the tools and the MRL criteria to gain consensus on 
ratings for each category. Honeywell's Manufacturing Maturity Model, 
with input from these enabling tools, is used to develop an MRL score 
for the product. These assessments provide early producibility 
evaluations essential to mitigating design-driven risks. Since many 
producibility issues are driven by early design architecture 
decisions, these tools provide a way to analyze these decisions early 
and make the necessary performance and producibility trades through 
"virtual prototyping" long before actual hardware is built. The MRL 
score provides the necessary framework to ask the questions that such 
an analysis needs to answer. 

After the MRL assessment is complete and the MRL scores and risk- 
mitigation plans are approved, the MRL analysis and risk mitigations 
are incorporated into the daily schedule of the program office. The 
office continually monitors the MRL levels, updating them and working 
toward its risk mitigation goals. 

Best Practice: Leading Firms Prove Out Manufacturing Tooling, 
Equipment, and Processes before Entry into Production: 

Companies we visited spent years prior to production developing and 
proving out their manufacturing processes, including building test 
articles on pilot production facilities to perfect these processes. 
This allowed them to perfect and validate these processes, eliminate 
waste and scale up gradually to the required manufacturing level. They 
reduce errors and inefficiencies with the purpose of retiring 
manufacturing risks. 

GE Aviation officials told us that certain advanced manufacturing 
technologies achieve significant cost savings by getting the costs 
lower earlier in the process and decreasing cycle time for faster 
implementation. An example of manufacturing techniques or processes 
that have made a big difference in costs, accuracy, and reliability 
include processes for drilling small shaped holes for turbine airfoils. 

GE Aviation's Turbine Airfoils Lean Lab provides a mock-up of a 
production facility or process, where such technologies and production 
processes can be tested to eliminate waste, scrap, and excess steps. 
They focus on one part family or process, such as the turbine airfoil 
shaped-hole manufacturing. The turbine airfoil is a part of the jet 
engine that generates power--it extracts horsepower from the high- 
temperature, high-speed combusted gasses. Turbine airfoil blades 
require hundreds of cooling holes that help maintain part integrity at 
elevated operating temperatures. Traditionally, round holes were used, 
but the technology has evolved to compound-angle-shaped holes, which 
improve cooling effectiveness and reduce engine stress. These type of 
holes cannot be economically produced by traditional methods and 
require improved manufacturing techniques. Advanced laser drilling was 
determined to be feasible, and GE Aviation decided to initiate the 
program through the Lean Lab to ensure manufacturing readiness of the 
process. 

GE Aviation officials compared their processes in this case to DOD's 
MRLs. Prior to entering their gated process, they began making 
investments in potential technologies, including tooling (MRL 1-3). As 
the gated process began, risks were identified and risk-abatement 
plans were put in place (MRL 4). GE Aviation then set up the Lean Lab 
to test the way the airfoil would actually be built. New processes 
were introduced that included new laser methods for hole drilling, 
improved robotic technology, machining, and grinding (MRL 5-6). The 
managers then ran the pilot production line for some time to 
manufacture these airfoils using actual production operators to be 
confident that the process would translate to the production line. 
Adjustments were made to improve efficiency and retested on the line 
until they were satisfied that they had worked out the best 
procedures. GE had tooling-design experts on the team at the Lean Lab 
to provide rapid part and tool manufacturing. Processes were brought 
into statistical control in order to take the complexity out of 
manufacturing, simplify the process, and reduce waste (MRL 7-8). They 
then dismantled the production line at the Lean Lab, took it to the 
manufacturing facility, and set it up exactly the same, with no 
variations allowed (MRL 9). This seamless introduction of the new 
manufacturing technology and the lean principles developed in the lab 
are expected to save many millions of dollars across GE Aviation, on 
production of this part family alone. Figure 6 shows a photo of GE 
Aviation's Lean Lab setup.

Production Processes:

GE Healthcare provides another example of proving out manufacturing 
processes prior to production in their development of the Gemstone 
scintillator for use on their CT Scanners. In 2003, the technology for 
this transitioned into the firm's formal gated process or product 
start-up, and it began a detailed and extensive development of the 
manufacturing process. The firm built a pilot plant for this purpose 
and began manufacturing the composite in increasing amounts. In this 
first pilot plant, it was able to process the materials in increased 
quantities from what it produced in the lab. GE Healthcare verified 
that it had the right technologies to minimize manufacturing risks. In 
the laboratory environment, the firm had already answered the question 
"Can this composite be made with the desired properties?" and now 
asked "Can it be made with sufficient yield and quality to be 
manufactured in the desired amounts?" This early engagement with 
manufacturing enabled the firm to develop the process and reduce 
errors and inefficiencies with the purpose of reducing manufacturing 
risks. 

GE Healthcare then built a second pilot production plant that further 
increased the amount produced above that of the first pilot plant. The 
firm continued its focus on gaining knowledge early, but on a larger 
scale: building the pilot plants was important to perfecting the 
process and gaining knowledge about the material's producibility. At 
this stage, which coincides with MRL 8, it eliminated most of the 
technical risks involved in manufacturing the material. The firm then 
began to build its full-scale facility, which was ready 18 months 
before product launch. 

When the full-scale production facility was completed, further scale-
up of the material's manufacturing became the focus. Changes to the 
design were made as needed to facilitate this. Any remaining 
manufacturing risks were eliminated prior to entry into the next 
stage, the product-validation stage. The Food and Drug Administration 
requires validation of finished medical devices. GE Healthcare told us 
that this means that all the equipment, processes, procedures, and 
factory workers are the same as will be used in actual production. 
Through use of the pilot plants to perfect the manufacturing of the 
scintillator material, GE Healthcare was able to produce production-
representative material to satisfy this requirement. 

Best Practice: Commercial Firms Work Closely with Suppliers, Who Must 
Meet High Quality Standards for Parts and Supplies: 

Commercial firms focus on developing strong relationships with their 
suppliers to ensure quality parts are provided in a timely manner. 
This begins with rigorous supplier-selection criteria to create a 
strong supplier base to provide quality parts. Similarly, DOD's MRL 
supply-chain thread focuses on supplier capability throughout the 
acquisition life cycle, from as early as pre-milestone A (MRL 3), 
where initial assessment of the supply chain begins, through MRL 5, 
where supply-chain sources have been identified, and continuing to MRL 
8, where the supply-chain should be stable and adequate to support low-
rate production. Commercial firms generally have long-term 
relationships with these suppliers and can identify the supplier that 
is the best source of material or parts early, well before production 
begins. Leading commercial firms apply the same standards to these 
suppliers as they apply to their own manufacturing processes, such as 
ISO 9000[Footnote 21] or other quality standards. Throughout product 
development and production, they establish effective communications 
with their suppliers so they can continually assess their performance. 
These firms work closely with their suppliers to retain these 
beneficial relationships, providing training where necessary and 
assistance if manufacturing problems arise. 

GE Healthcare suppliers have to be validated before production begins, 
but qualifying them starts in the design phase. Suppliers are expected 
to meet the ISO 9000 standards and the Food and Drug Administration's 
medical devices standards, but GE Healthcare's own standards are more 
stringent that those. The supplier-qualification process ensures that 
suppliers meet GE Healthcare's requirements, have a quality system 
that provides the appropriate controls for the part provided and meet 
regulations and requirements of multiple agencies, such as the Food 
and Drug Administration. Once a supplier is qualified, it becomes an 
approved supplier. 

GE Healthcare also audits most of its suppliers and looks for issues 
such as lapsed ISO 9000 certification or a failed review. If it finds 
these things, GE Healthcare will ask the supplier for a plan to 
correct the deficiency and reaudit the supplier. GE Healthcare does 
annual risk assessments on the suppliers, based on data gathered 
during these audits, with sole-source or single-source suppliers being 
a high risk. If a supplier falls out of qualified status, GE 
Healthcare will do more frequent assessments. It constantly monitors 
the suppliers for quality. It helps the supplier get to the quality 
needed, but quality goals must be met. 

Siemens is a global company that employs about 70,000 people in the 
United States. We visited Siemens Mobility Division, which builds 
light rail cars for public transit. Siemens places special emphasis on 
its supplier relationships, since it knows its suppliers can contract 
to other rail-car builders, as there is competition for suppliers in 
this market. If it has a good relationship with its suppliers, it can 
continue to benefit from the relationships with high-quality 
suppliers. Once it qualifies a supplier, it takes the responsibility 
for keeping the supplier qualified, providing technical assistance if 
necessary to keep the supplier in its pipeline. Even as early as the 
bid phase of the contract, Siemens knows who it will need as suppliers 
and if any particular supplier is new or challenged in some respect. 

Siemens applies a three-step supplier-qualification process to its 
suppliers. This starts with a supplier self-assessment. The firm's 
supplier-qualification personnel then visit the supplier's plant and 
evaluate the supplier on the same self-assessment form, to determine 
if the supplier will make it to the vendor-qualification list. Once a 
supplier is on the approved vendor-qualification list, Siemens does 
risk ratings for these vendors to be sure it can keep them on the 
qualified-vendor list. The firm updates these assessments if the 
vendor situation changes, rating the vendor at low risk if it is fully 
qualified and working with it if some aspects are not qualified. 
Siemens takes responsibility for keeping the approved suppliers 
qualified, since finding and qualifying new vendors can be time- 
consuming and risky. It tries not to overload any one supplier, 
because some of their suppliers are small or specialty operations, so 
it keeps a pool of qualified suppliers for as many parts or materials 
as it can. 

Commercial Firms Require That Manufacturing Processes Be in Control 
Earlier Than DOD's MRLs: 

Although the firms we visited used manufacturing readiness criteria 
similar to DOD's proposed MRLs, one important difference we observed 
is that the commercial best practice is to have manufacturing 
processes in control prior to the production decision, while DOD's 
MRLs require manufacturing processes and procedures to be established 
and controlled during MRL 9, which occurs after the milestone C 
production decision, which authorizes a program to enter low-rate 
initial production, or equivalent.[Footnote 22] Although DOD's MRLs 
incorporate many of the commercial manufacturing best practices into 
their manufacturing design and implementation criteria, the process 
controls criteria would be met too late in the process to achieve 
their full effect. DOD's MRL matrix states that low-rate production 
yield and rate targets should be achieved at MRL 9, after the 
production decision has been made. The commercial firms we talked to 
emphasized that production processes must be in control before this 
decision is made. They realize that they are unable to make 
predictions about production performance until the process is stable 
and defects are predictable. Not achieving process control could 
result in low quality, extensive rework and waste, and not meeting 
cost and schedule targets. Firms established pilot lines to prove out 
production material, processes, and tooling, and worked to get 
processes under control before the system could move from the pilot 
line to production line. Figure 7 shows a depiction of the commercial 
manufacturing process approach.

Quality Products:

The companies we visited used various approaches to build process 
capability and provide timely information on whether manufactured 
components, subsystems, or systems meet design specification. For 
example, GE Aviation uses a statistical measurement, called Z sigma 
level, to determine whether its processes have been brought under 
control or if variations in its manufacturing process could affect the 
quality of the product. The product is not moved into production until 
the firm is satisfied that these processes are in control. Similarly, 
GE Healthcare's milestone process requires that a set of quality 
targets are part of the program and that those quality targets are 
met. Measures of process control vary from company to company, such as 
using yield or scrap and rework rates or sigma levels, but each looks 
carefully at those measures to ensure they carried no product-quality 
risk and uses this information to determine if the product is ready to 
be manufactured. 

Two Successful DOD Programs Used Criteria Similar to Commercial Firms: 

Two DOD programs, the Army's Lakota aircraft and the Missile Defense 
Agency's Standard Missile 3 Block 1A, that had successful 
manufacturing outcomes employed some of the same practices as leading 
commercial firms. Both used a type of manufacturing readiness criteria 
to evaluate whether the programs were ready to enter into production 
and both programs focused on manufacturability as a key indicator of 
program success, using well-developed technology and a conservative 
approach in design and development. 

The Lakota aircraft, a light utility helicopter that conducts 
noncombat missions, was a mature aircraft design when the Army entered 
into the contract with the European Aeronautic Defence and Space 
Company to purchase this commercially available helicopter. The 
program shows how careful attention to manufacturing readiness can 
reduce program risks. According to program office officials, the 
contractor was chosen in part because of its manufacturing track 
record, and it completed extensive planning, both internally and with 
its supplier base, to ensure on-time and reliable deliveries. 
Production planning and preparation were accomplished, including 
assessments of the manufacturing processes, capabilities, and 
facilities. These assessments determined that the program was low risk 
and ready for full-rate production. The Lakota is currently in full-
rate production and has met its cost and schedule targets. 

The Standard Missile 3 is a ship-based, antiballistic missile used by 
the Aegis ballistic missile defense system. Similar to the Lakota, the 
system met its cost and schedule goals by using an incremental, low- 
risk approach. Like the commercial firms we visited, the program built 
knowledge through the use of a type of manufacturing readiness 
criteria, which allowed the early identification of risk and 
implementation of mitigation strategies. The Standard Missile 3 Block 
IA was also on target for manufacturing cost and schedule and reported 
a lower cost per unit than was originally estimated on its production 
buys. As in the successful commercial firms we visited, manufacturing 
issues were considered very early in the design phase, leading to 
minimal changes in the program from flight test to production. 

MRLs Are Hampered by Lack of an Agencywide Policy and Manufacturing 
Workforce Concerns: 

While acceptance of MRLs is growing within DOD and the defense 
industry, the services' leadership appears to be resistant, and 
adoption efforts have been slow. For example, obtaining agreement on a 
policy that would institutionalize MRLs defensewide has proven 
difficult. Concerns raised by the military-service policymakers have 
centered on when and how the MRL assessments would be used. Officials 
responsible for the draft policy have promoted MRLs as an initiative 
that can address the manufacturing element in the design and 
production of weapon systems, citing commercial best practices that 
employ similar methods, and benefits derived from pilot programs. 
While extensive efforts have been made to promote the benefits of MRLs 
in support of a revised draft policy, it has taken nearly 2 years to 
allay concerns and it has not yet been approved. DOD is likely to face 
serious challenges even if an agreement is reached to approve the 
policy, however, because the number of DOD's production and 
manufacturing career-field employees has diminished, particularly 
within the Air Force. Although the services are at the beginning 
stages of revitalizing their production and manufacturing workforce, 
DOD currently does not have adequate in-house expertise with the 
requisite knowledge to assess manufacturing throughout DOD. 
Essentially, the military services and Defense Contract Management 
Agency have identified knowledge and manpower gaps in their 
manufacturing workforce and believe that any initiative deploying MRLs 
defensewide could be hampered as a result. 

Draft Policy to Institutionalize MRLs Has Proven Difficult, but the 
DOD Community Is Starting to See Its Value: 

While acceptance of MRLs is growing within DOD and the defense 
industry, the Army's, Navy's, and Air Force's leadership appears to be 
resistant and adoption efforts have been slow. For example, a July 
2008 draft MRL policy memorandum garnered disagreement among the 
military-service policymakers. The military services' leadership 
agreed that MRLs provide value in the early acquisition phases but 
disagreed with the policy's intent to formalize the process. For 
example, the MRL policy memorandum stated that on the basis of 
analyses by GAO and the Defense Science Board--as well as positive 
results on two Air Force pilot programs--that acquisition category I 
programs be assessed using the MRL scale. In particular, the draft 
policy included provisions that would require programs at milestone B 
to be assessed at MRL 6 or beyond for all critical technologies; 
programs at milestone C to be assessed at MRL 8 for all critical 
technologies; procedures to be coordinated for including assessments 
of manufacturing readiness in addition to technology readiness 
assessments at milestone B and C; and incorporation of guidance into 
training materials and guidebooks on best practices for addressing 
manufacturing from the earliest stages of development through 
production and sustainment. 

In response to the draft policy, each of the military services issued 
memorandums in July 2008 to the Under Secretary of Defense 
(Acquisition, Technology and Logistics) or the Director, Defense 
Research and Engineering, stating they support MRLs and their use 
earlier in the acquisition process but they saw limited value in doing 
formal assessments prior to milestone C. In general, the services had 
concerns on when and how MRL assessments would be used. More 
specifically, their concerns included the following: 

* Evaluation results that could be used as the basis for go/no go 
decisions. 

* A growing number of assessments being levied on acquisition programs. 

* Resources required to prove out multiple production lines in a 
competitive prototyping environment during the technology-development 
phase. 

Since 2008, officials responsible for the draft policy memorandum have 
been working to address concerns raised by the services. According to 
the working group, most concerns pointed to a need to clarify how the 
information is intended to be used by decision makers at key 
milestones, particularly at the earlier milestones. According to the 
working group officials we interviewed, the intent is to inform 
decision makers with critical information--such as manufacturing risk 
and readiness measures, as appropriate to the phase of acquisition--so 
that knowledge-based decisions can be made earlier in the process to 
influence better outcomes in terms of cost and schedule in the later 
acquisition phases. Moreover, they cite that similar methods are 
employed by leading commercial firms as a best practice, plus the fact 
that MRL pilot programs have already demonstrated significant 
benefits. The revised MRL draft policy has not yet been approved. 
Officials familiar with the status of the draft policy stated that the 
leadership at one of the military services is still opposed to the 
idea of standardizing MRLs across DOD, and efforts to get approval 
have not yet occurred within the Office of the Director, Defense 
Research and Engineering. 

DOD experienced similar problems introducing technology readiness 
levels. There was opposition to the use of technology readiness 
levels, but they became a standard for programs to follow, and the 
standard that technologies should be demonstrated in a relevant 
environment became a statutory requirement for all major acquisition 
programs seeking to enter system development.[Footnote 23] Programs 
report benefits from using technology readiness levels. 

Some officials believe that MRLs could significantly reduce cost 
growth. For example, the Army and Air Force have reported MRLs were a 
factor that contributed to benefits of hundreds of millions of dollars 
in reduced program costs, improved schedule, and better performance of 
products. 

MRL Acceptance Is Growing within DOD and Defense Industry: 

A number of Army, Air Force, and Missile Defense Agency programs--as 
well as defense contractors--have embraced MRLs as the method for 
assessing manufacturing maturity, risk, and readiness. For example, 
some Army commands have opted to use them on their science and 
technology efforts that have manufacturing elements, and have 
developed a formal process for identifying them. Similarly, two of 
three Air Force product centers under the materiel command--the 
Aeronautical Systems Center and the Air Armament Center--have recently 
issued local policy that mandate the use of MRLs. For example, in a 
policy memorandum by the Aeronautical Systems Center, dated October 
13, 2009, all programs are now required to have manufacturing 
readiness assessments using MRLs, prior to each major milestone 
review. The memorandum acknowledged that the transition to production 
has historically been challenging for many programs and that 
manufacturing assessments are a key tool to ensure that programs are 
ready to begin production. The Missile Defense Agency has included 
MRLs as part of their assessment criteria. In addition, senior missile 
defense manufacturing personnel have developed and conducted training 
on how to conduct these assessments. 

Similarly, a number of defense contractors have implemented MRLs as a 
discipline for identifying, managing, and communicating manufacturing 
risk and readiness. These contractors report a number of benefits 
using the MRLs, including reductions in program costs and improved 
production schedule. For example, in 2006, Raytheon participated in 
pilot MRL program assessments involving the Advanced Medium-Range Air-
to-Air Missile and a portfolio of other programs and concluded the 
approach makes good business sense to lower risk. Raytheon claimed 
cost reductions of 30 percent or more could be achieved by using MRLs. 
Raytheon officials state that the combination of technology and 
manufacturing assessment processes changes the culture by driving a 
collaborative partnership between programs, design, and manufacturing 
engineering earlier in the product-development life cycle where 
maturity efforts can have the greatest effect on improving program 
affordability and predictability. As a result, Raytheon is deploying 
MRLs as a standard across the organization. Lockheed Martin is 
exploring ways to integrate MRLs within its existing review processes. 
As previously discussed, Honeywell adopted MRLs for use on both its 
defense and commercial products, and developed several models as an 
analysis-based approach to quantify their producibility risks. 

Manufacturing Workforce Knowledge and Manpower Gaps May Impede 
Implementation of MRLs: 

The services are in the beginning stages of revitalizing their 
manufacturing workforce, largely in response to a February 2006 
Defense Science Board task force report on "The Manufacturing 
Technology Program: A Key to Affordably Equipping the Future Force." 
The report acknowledged that both the manufacturing expertise in the 
workforce and program funding have declined, thus eliminating much of 
the engineering and manufacturing talent across DOD and the industrial 
base. The report concluded that what was once a promising career field 
in the military services--with promotion paths, training, and 
professional development--has been systematically eliminated over the 
past few decades. Table 4 shows the decrease in the manufacturing 
career field across DOD from 2001 to 2007.

[End of table] 

As indicated, DOD's manufacturing career workforce trends show an 
overall decline, with the Army and Air Force having had the biggest 
declines at 14 percent and 37 percent, respectively. According to a 
DCMA official, the agency experienced about a 30 percent decrease 
during the same timeframe. An Army official responsible for workforce 
planning activities noted, however, there are no positions designated 
specifically for manufacturing, which make it difficult to determine 
the true career workforce numbers in this category. Fewer experts mean 
that fewer people at both the working level and in leadership 
positions understand the processes involved in developing and 
manufacturing defense systems and their importance in producing high-
quality and reliable systems. Further, fewer people are capable of 
conducting production-readiness reviews, evaluating industry's work on 
programs, and staying abreast of industry research and development. 
According to a recent study, of major concern is that recent estimates 
show 30 percent of the civilian manufacturing workforce--classified as 
production, quality, and manufacturing--are eligible for full 
retirement, and approximately 26 percent will become eligible for full 
retirement over the next 4 years. This means DOD will soon have an 
exodus of its manufacturing workforce and, accordingly, must plan for 
this eventuality. 

Although the services are at the beginning stages of revitalizing 
their production and manufacturing workforce, program officials 
believe they currently do not have the in-house expertise with the 
requisite knowledge to assess manufacturing, if MRLs were to be 
mandated and deployed across DOD. For example, in interviews with 
career planning officials at the military services, most report that 
they have workforce challenges in manufacturing knowledge gaps or 
insufficient number of personnel to conduct the work, or both. The 
Defense Contract Management Agency reported similar manufacturing 
knowledge gaps due to a lack of focus in this area, but it now has new 
leadership in place and is establishing plans to address these 
deficiencies. Essentially, these knowledge deficiencies affect many 
areas, such as policy support for programs, the ability to develop an 
effective strategic plan and investment strategy for manufacturing 
technology, the ability to implement MRLs and conduct assessments, and 
the ability to effectively and affordably acquire high-quality weapon 
systems. 

Conclusions: 

MRLs, resourced and used effectively, offer the potential for DOD to 
achieve substantial savings and efficiencies in developing and 
acquiring weapon systems. MRLs have been shown to work in reducing the 
cost and time for developing technologies and producing systems. 
Moreover, they have been shown to work on individual programs, and 
some Army commands and Air Force centers have adopted them. They are 
consistent with commercial best practices and have even been adopted 
by some defense firms. Yet, they have not been adopted DOD-wide. MRLs 
are being met with resistance similar to that experienced by 
technology readiness levels when they were first introduced. However, 
technology readiness levels are now widely accepted and used across 
DOD. 

While MRLs represent a common body of knowledge and reflect many of 
the practices used by leading commercial companies, there is room for 
improvement. Criteria used for getting manufacturing processes under 
control are still not specific enough, allowing demonstration of 
controls to occur too late in the process--after the milestone C 
decision authorizing low-rate initial production--whereas commercial 
firms require that critical processes be in control earlier. While 
MRLs represent positive change, unless these criteria are strengthened 
at the time a production decision is made, DOD will have missed an 
opportunity to reduce the risk of continued cost growth on acquisition 
programs. Moreover, use of MRLs would be enhanced by the development 
of analytical tools, such as those used by Honeywell, to support MRL 
assessments. 

A serious concern is that DOD's in-house manufacturing workforce has 
been diminishing for decades and that, therefore, could hamper 
successful implementation of MRLs. Unless DOD develops long-range 
plans to build its in-house manufacturing workforce, it may not be 
able to realize the full potential of integrating manufacturing 
readiness levels into its processes. 

Recommendations for Executive Action: 

To ensure that DOD is taking steps to strengthen and improve the 
producibility and manufacturing readiness of technologies, weapon 
systems, subsystems, or manufacturing processes, we recommend that the 
Secretary of Defense do the following: 

* Require the assessment of manufacturing readiness across DOD 
programs using consistent MRL criteria as basis for measuring, 
assessing, reporting, and communicating manufacturing readiness and 
risk on science and technology transition projects and acquisition 
programs. 

* Direct the Office of the Director, Defense Research and Engineering 
to examine strengthening the MRL criteria related to the process 
capability and control of critical components and/or interfaces prior 
to milestone C, or equivalent, for low-rate initial production 
decision. 

* Direct the Office of the Director, Defense Research and Engineering 
to assess the need for analytical models and tools to support MRL 
assessments. 

* Assess the adequacy of the manufacturing workforce knowledge and 
skills base across the military services and defense agencies and 
develop a plan to address current and future workforce gaps. 

Agency Comments and Our Evaluation: 

DOD provided us written comments on a draft of this report. DOD 
partially concurred with our recommendation to require the assessment 
of manufacturing readiness across DOD programs using MRL criteria, and 
concurred with our other recommendations. Their comments can be found 
in appendix IV of this report. 

In its comments, DOD partially concurred with the recommendation that 
DOD programs be required to assess manufacturing readiness using 
consistent MRL criteria as the basis for measuring, assessing, 
reporting, and communicating manufacturing readiness and risk on 
science and technology transition projects and acquisition programs. 
DOD cites the Department of Defense Instruction 5000.02 as reflecting 
on manufacturing throughout the acquisition life cycle and, 
specifically, establishing a framework to continually assess and 
mitigate manufacturing risks. In its remarks, DOD states that the 
manufacturing readiness criteria will be tailored to programs and 
embedded into reviews and assessment templates, including systems 
engineering reviews, preliminary design reviews, and critical design 
reviews as well as acquisition phase exit criteria. 

While we are encouraged by DOD's plans to incorporate manufacturing 
readiness criteria into various assessments, we are concerned about 
the absence of any reference to MRLs, which identify specific 
benchmarks for each acquisition phase. It is unclear from DOD's 
comments whether it intends to use a common definition of 
manufacturing readiness as acquisition phase exit criteria or whether 
the exit criteria will be decided on a case-by-case basis. While 
tailoring to individual programs is appropriate, tailoring must take 
place in the context of well-understood criteria for moving from phase 
to phase. A hallmark of the commercial programs we have looked at in 
this and other reviews is the reliance on disciplined processes for 
assessing readiness to proceed into more costly development and 
production phases. Firm criteria are needed to identify and address 
producibility and manufacturing risks on a timely basis, before they 
result in expensive production problems. 

We also received technical comments from DOD, which have been 
addressed in the report, as appropriate. 

We are sending copies of this report to the Secretary of Defense; the 
Secretary of the Army; Secretary of the Navy; Secretary of the Air 
Force; Director, Missile Defense Agency; Director, Defense Contract 
Management Agency; and Office of Management and Budget. In addition, 
the report will be made available at no charge on the GAO Web site at 
[hyperlink, http://www.gao.gov].

Appendix I: Scope and Methodology: 

This report compares the Department of Defense (DOD) and its large 
prime contractors' manufacturing practices with those of leading 
commercial companies--with a focus on improving the manufacturing of 
defense weapon systems. Specifically, we assessed (1) the 
manufacturing problems experienced by DOD, (2) how manufacturing 
readiness levels (MRLs) can address DOD's manufacturing problems, (3) 
how proposed MRLs compare to manufacturing best practices of leading 
commercial companies, and (4) the challenges and barriers to 
implementing MRLs at DOD. 

To identify the manufacturing problems experienced by DOD, we 
performed an aggregate analysis of DOD programs from our annual 
assessment database. We also conducted case studies of four programs 
with known cost and schedule problems to make observations on the 
types of problems DOD weapon systems may experience. The programs we 
reviewed, along with the prime contractors responsible for developing 
the systems, are: 

* Joint Air-to-Surface Standoff Missile, an air-to-surface missile 
funded by the Air Force and developed by Lockheed Martin; 

- Exoatmospheric Kill Vehicle, a ballistic-missile interceptor funded 
by the Missile Defense Agency and developed by Raytheon; 

- Electromagnetic Aircraft Launch System, a launch system for aircraft 
carriers funded by the Navy and developed by General Atomics; and: 

- H-1 helicopter upgrade, tactical utility and attack helicopters 
funded by the Navy and developed by Bell Helicopter. 

To evaluate the four DOD weapon programs, we examined program 
documentation, such as acquisition decision memos and production 
readiness reviews, and held discussions with manufacturing and systems 
engineering officials from DOD program offices, the prime contractors, 
and the Defense Contract Management Agency. Based on the information 
gathered through interviews conducted and documentation synthesized, 
we identified commonalities among the case studies. 

To determine how MRLs can address the manufacturing problems 
experienced by defense programs, we conducted interviews with 
officials from the Office of Secretary of Defense, Office of the 
Director, Defense Research & Engineering, Joint Defense Manufacturing 
Technology Panel working group, National Center for Advanced 
Technologies, National Defense Industrial Association, and Defense 
Acquisition University on their observations on MRLs. We also reviewed 
the MRL deskbook, matrix (risk areas), analyses, and training 
materials. We also conducted interviews with Army, Navy, and Air Force 
officials who were involved or familiar with the pilot tests of MRLs 
on various programs. The pilot programs we examined at the military 
services include the following: 

* Army--micro electro-mechanical systems inertial measurement unit, 
micro electro-mechanical systems safety arm, ferroelectric and micro 
electro-mechanical systems phase shifter, low-cost materials for 
improved protection, rotorcraft cabin floor structure, embedded 
sensors, and armor manufacturing; 

* Air Force--MQ-9 Reaper, F-35 Joint Strike Fighter induct inlet, high-
durability hot exhaust structures, F-135 Pratt & Whitney propulsion 
system, sensor hardening for tactical systems, and X-Band thin array 
radar; and: 

* Navy--P-8A aircraft. 

To identify practices and criteria used by leading commercial 
companies that can be used to improve DOD's manufacturing process, we 
selected and visited five companies based on several criteria: 
companies that (1) make products that are comparable to DOD in terms 
of complexity, (2) are recognized as leaders in developing 
manufacturing readiness criteria, or (3) have won awards for their 
manufacturing best practices, or a mix of the above. We met with these 
companies to discuss their product-development and manufacturing 
practices and the steps that they take to mitigate manufacturing 
risks, ensure manufacturing readiness, and improve supplier quality. 
We met with these companies to discuss their product-development life 
cycle and the methods and metrics they use to measure manufacturing 
maturity and producibility; manufacturing risk management; supplier 
management; and the key factors in the company's successful 
manufacturing outcomes. We generalized much of the information due to 
the proprietary nature of the data relating to their manufacturing 
processes. Several companies provided data on specific processes or 
products that they agreed to allow us to include in this report. We 
reported on four of the five companies we visited. The five companies 
we visited include the following: 

* GE Aviation, a leading aerospace company, whose portfolio includes 
commercial engines and services, military engines and services, 
business and general aviation, engine components, and aviation 
systems. We met with manufacturing and quality officials in 
Cincinnati, Ohio, and discussed their manufacturing practices and 
manufacturing maturity metrics. We also toured their Lean Lab 
production facility and saw how these practices were applied. 

* GE Healthcare, which manufactures a range of products and services 
that includes medical imaging and information technologies and medical 
diagnostics. We met with manufacturing officials at their Milwaukee, 
Wisconsin, plant and discussed their manufacturing practices, 
including the development and manufacturing of their Gemstone 
scintillator for use on advanced CT scanners. 

* Honeywell Aerospace, a global provider of integrated avionics, 
engines, systems, and services for aircraft manufacturers, airlines, 
business and general aviation, and military and space operations. We 
met with manufacturing officials at their Phoenix, Arizona, facility 
and discussed their manufacturing maturity processes and the models 
and tools they used to assess this. 

* Siemens Mobility, a division of Siemens that develops and builds 
light rail cars for the North American market. We met with 
manufacturing and procurement officials at their Sacramento, 
California, manufacturing and assembly plant to discuss the 
manufacturing processes used in building their rail cars and their 
supplier management practices. 

* Toyota Motor Engineering and Manufacturing is responsible for 
Toyota's engineering design, development and manufacturing activities 
in North America. We met with officials in their production 
engineering division in Erlanger, Kentucky, and also in their Toyota 
Technical Center located in Ann Arbor, Michigan, and discussed their 
vehicle development process and their methods for assuring supplier 
quality. 

At each of the companies, we interviewed senior management officials 
knowledgeable about the manufacturing methods, techniques, and 
practices used throughout manufacturing and product development to 
ensure manufacturing maturity and producibility of their products. In 
particular, we discussed their (1) product development life cycle and 
the methods, metrics, and tools used to determine manufacturing 
maturity and producibility, (2) methods for identifying and mitigating 
risks in manufacturing a product, and (3) methods for supplier 
management to provide steady supply of quality parts. 

In addition, we compared the practices of commercial firms to two 
major defense weapon systems known to be producing systems within cost 
and schedule goals and with successful manufacturing outcomes. To 
evaluate these two programs, we examined program documentation and 
held discussions with program and contracting officials. The two 
systems we reviewed, along with the prime contractors responsible for 
developing the systems, are: 

* Lakota aircraft, a light utility helicopter that conducts noncombat 
missions, funded by the Army and developed by the European Aeronautic 
Defence and Space Company; and: 

* Standard Missile 3 Block 1A, a ship-based antiballistic missile, 
funded by the Missile Defense Agency and developed by Raytheon. 

To determine the challenges and barriers to MRL implementation 
efforts, we interviewed officials who were involved with the draft 
policy to standardize MRLs, as well as the military-service policy 
organizations that commented on the proposal. We also synthesized the 
information gathered at the various levels throughout the defense 
community to determine the issues surrounding MRLs as well as their 
merits. These DOD organizations include the Office of the Secretary of 
Defense, each of the military-service policy groups and program 
offices, the Office of the Director, Defense Research and Engineering, 
Systems and Software Engineering, and Joint Defense Manufacturing 
Technology Panel. To obtain an understanding of the workforce 
challenges in manufacturing, we reviewed selected documentation--such 
as Defense Science Board studies--and interviewed officials at each of 
the military services and Defense Contract Management Agency who were 
responsible for workforce planning activities and revitalization 
initiatives. 

We conducted this performance audit from January 2009 to February 2010 
in accordance with generally accepted government auditing standards. 
These standards require that we plan and perform the audit to obtain 
sufficient, appropriate evidence to provide a reasonable basis for our 
findings and conclusions based on our audit objectives.

Appendix II: Manufacturing Readiness Level (MRL) Definitions: 

MRL 1--Basic Manufacturing Implications Identified: 

This is the lowest level of manufacturing readiness. The focus is to 
address manufacturing shortfalls and opportunities needed to achieve 
program objectives. Basic research (i.e., budget activity 6.1 funds) 
begins in the form of studies. 

MRL 2--Manufacturing Concepts Identified: 

This level is characterized by describing the application of new 
manufacturing concepts. Applied research (i.e., budget activity 6.2 
funds) translates basic research into solutions for broadly defined 
military needs. Typically this level of readiness in the science and 
technology environment includes identification, paper studies, and 
analysis of material and process approaches. An understanding of 
manufacturing feasibility and risk is emerging. 

MRL 3--Manufacturing Proof of Concept Developed: 

This level begins the validation of the manufacturing concepts through 
analytical or laboratory experiments. This level of readiness is 
typical of technologies in the science and technology funding 
categories of Applied Research and Advanced Development (i.e., budget 
activity 6.3 funds). Materials or processes, or both, have been 
characterized for manufacturability and availability but further 
evaluation and demonstration is required. Experimental hardware models 
have been developed in a laboratory environment that may possess 
limited functionality. 

MRL 4--Capability to Produce the Technology in a Laboratory 
Environment: 

This level of readiness is typical for science and technology programs 
in the budget activity 6.2 and 6.3 categories and acts as exit 
criteria for the materiel solution analysis phase approaching a 
milestone A decision. Technologies should have matured to at least 
technology readiness level 4. This level indicates that the 
technologies are ready for the technology-development phase of 
acquisition. At this point, required investments, such as 
manufacturing technology development, have been identified. Processes 
to ensure manufacturability, producibility, and quality are in place 
and are sufficient to produce technology demonstrators. Manufacturing 
risks have been identified for prototype build, and mitigation plans 
are in place. Target cost objectives have been established and 
manufacturing cost drivers have been identified. Producibility 
assessments of design concepts have been completed. Key design 
performance parameters have been identified as well as any special 
tooling, facilities, material handling, and skills required. 

MRL 5--Capability to Produce Prototype Components in a Production- 
Relevant Environment: 

This level of maturity is typical of the midpoint in the technology- 
development phase of acquisition, or in the case of key technologies, 
near the midpoint of an advanced technology-demonstration project. 
Technologies should have matured to at least technology readiness 
level 5. The industrial base has been assessed to identify potential 
manufacturing sources. A manufacturing strategy has been refined and 
integrated with the risk-management plan. Identification of enabling/ 
critical technologies and components is complete. Prototype materials, 
tooling and test equipment, as well as personnel skills, have been 
demonstrated on components in a production-relevant environment, but 
many manufacturing processes and procedures are still in development. 
Manufacturing technology development efforts have been initiated or 
are ongoing. Producibility assessments of key technologies and 
components are ongoing. A cost model has been constructed to assess 
projected manufacturing cost. 

MRL 6--Capability to Produce a Prototype System or Subsystem in a 
Production-Relevant Environment: 

This MRL is associated with readiness for a milestone B decision to 
initiate an acquisition program by entering into the engineering and 
manufacturing development phase of acquisition. Technologies should 
have matured to at least technology readiness level 6. It is normally 
seen as the level of manufacturing readiness that denotes completion 
of science and technology development and acceptance into a 
preliminary system design. An initial manufacturing approach has been 
developed. The majority of manufacturing processes have been defined 
and characterized, but there are still significant engineering or 
design changes, or both, in the system itself. However, preliminary 
design of critical components has been completed and producibility 
assessments of key technologies are complete. Prototype materials, 
tooling and test equipment, as well as personnel skills have been 
demonstrated on systems or subsystems, or both, in a production-
relevant environment. A cost analysis has been performed to assess 
projected manufacturing cost versus target cost objectives and the 
program has in place appropriate risk reduction to achieve cost 
requirements or establish a new baseline. This analysis should include 
design trades. Producibility considerations have shaped system-
development plans. Industrial capabilities assessment for milestone B 
has been completed. Long-lead and key supply-chain elements have been 
identified. All subcontractors have been identified. 

MRL 7--Capability to Produce Systems, Subsystems, or Components in a 
Production-Representative Environment: 

This level of manufacturing readiness is typical for the midpoint of 
the engineering and manufacturing-development phase leading to the 
post-critical design review assessment. Technologies should be 
maturing to at least technology readiness level 7. System detailed 
design activity is underway. Material specifications have been 
approved and materials are available to meet the planned pilot-line 
build schedule. Manufacturing processes and procedures have been 
demonstrated in a production-representative environment. Detailed 
producibility trade studies and risk assessments are underway. The 
cost model has been updated with detailed designs, rolled up to system 
level, and tracked against allocated targets. Unit-cost reduction 
efforts have been prioritized and are underway. The supply chain and 
supplier quality assurance have been assessed and long-lead 
procurement plans are in place. Production tooling and test equipment 
design and development have been initiated. 

MRL 8--Pilot-Line Capability Demonstrated; Ready to Begin Low-Rate 
Initial Production: 

This level is associated with readiness for a milestone C decision, 
and entry into low-rate initial production. Technologies should have 
matured to at least technology readiness level 7. Detailed system 
design is essentially complete and sufficiently stable to enter low- 
rate production. All materials are available to meet the planned low- 
rate production schedule. Manufacturing and quality processes and 
procedures have been proven in a pilot-line environment and are under 
control and ready for low-rate production. Known producibility risks 
pose no significant challenges for low-rate production. The 
engineering cost model is driven by detailed design and has been 
validated with actual data. The Industrial Capability Assessment for 
milestone C has been completed and shows that the supply chain is 
established and stable. 

MRL 9--Low-Rate Production Demonstrated; Capability in Place to Begin 
Full-Rate Production: 

At this level, the system, component, or item has been previously 
produced, is in production, or has successfully achieved low-rate 
initial production. Technologies should have matured to at least 
technology readiness level 9. This level of readiness is normally 
associated with readiness for entry into full-rate production. All 
systems-engineering/design requirements should have been met such that 
there are minimal system changes. Major system design features are 
stable and have been proven in test and evaluation. Materials are 
available to meet planned rate production schedules. Manufacturing 
process capability in a low-rate production environment is at an 
appropriate quality level to meet design key-characteristic 
tolerances. Production risk monitoring is ongoing. Low-rate initial 
production cost targets have been met, with learning curves validated. 
The cost model has been developed for the full-rate production 
environment and reflects the effect of continuous improvement. 

MRL 10--Full-Rate Production Demonstrated and Lean Production 
Practices in Place: 

This is the highest level of production readiness. Technologies should 
have matured to at least technology readiness level 9. This level of 
manufacturing is normally associated with the production or 
sustainment phases of the acquisition life cycle. Engineering/design 
changes are few and generally limited to quality and cost 
improvements. System, components, or items are in full-rate production 
and meet all engineering, performance, quality, and reliability 
requirements. Manufacturing process capability is at the appropriate 
quality level. All materials, tooling, inspection and test equipment, 
facilities, and manpower are in place and have met full-rate 
production requirements. Rate production unit costs meet goals, and 
funding is sufficient for production at required rates. Lean practices 
are well established and continuous process improvements are ongoing.

DoD Response to GA0-10-439 Recommendations: 
GAO Draft Report Dated March 12, 2010: 
GAO-10-439 (GAO Code 120793): 

"Best Practice: DOD Can Achieve Better Outcomes By Standardizing The 
Way Manufacturing Risks Are Managed" 

Department Of Defense Comments To The GAO Recommendations: 

Recommendation 1: The GAO recommends that the Secretary of Defense 
require the assessment of manufacturing readiness across DoD programs 
using consistent MRL criteria as a basis for measuring, assessing, 
reporting, and communicating manufacturing readiness and risk on 
science and technology transition projects and acquisition
programs. 

DOD Response: Partially concur: The Department of Defense recognizes 
that mature manufacturing processes and readiness are critical to 
achieving predictable and successful program outcomes. It also 
recognizes the value in assessing manufacturing risks during science 
and technology research on technologies planned to be incorporated 
into acquisition programs. Department of Defense Instruction (DoDI) 
5000.02, Operation of the Defense Acquisition System, dated 8 December 
2008 reflects an increased focus on manufacturing throughout the 
acquisition lifecycle for programs of all acquisition categories. 
Specifically, it establishes a framework to continually assess and 
mitigate manufacturing risks during the Analysis of Alternatives, 
2366b certifications to Congress, Preliminary and Critical Design 
Reviews; and acquisition milestones. 

The Department's new manufacturing readiness criteria will form the 
basis for assessing pertinent science and technology efforts, and 
acquisition programs throughout the acquisition lifecycle on programs 
of all acquisition categories. These criteria will be a tool to 
identify relevant manufacturing risks which require mitigation. These 
manufacturing readiness criteria are expected to be tailored for 
programs and will be included in the Department's criteria for systems 
engineering technical reviews; the Department's templates for 
Preliminary Design Review/Critical Design Review reports; and 
acquisition phase exit criteria. These manufacturing readiness 
criteria will also be assessed as part of the Program Support Reviews 
which the Department conducts on Major Defense Acquisition Programs. 
These reviews evaluate manufacturing as part of an overall integrated 
program assessment. These manufacturing readiness criteria and 
products will be made available to government and industry. Their use 
by the Services on lower ACAT programs will also be encouraged. The 
Navy's Gate Review process currently assesses manufacturing risks but 
is being updated with the new manufacturing readiness criteria. 

Recommendation 2: The GAO recommends that the Secretary of Defense 
direct the Office of the Director, Defense Research and Engineering to 
examine strengthening the MRL criteria related to the process 
capability and control of critical components and/or interfaces prior 
to the Milestone C low rate initial production decision. 

DOD Response: Concur. Department of Defense Instruction 5000.02 
directs that programs at Milestone C have no significant manufacturing 
risks; that manufacturing processes have been effectively demonstrated 
in a pilot line environment; and manufacturing processes are under 
control (if Milestone C is full-rate production). While the Department 
notes that all manufacturing processes do not warrant the same level 
of process capability and control, appropriate levels of control are 
certainly warranted on a case by case basis. 

The Department will examine strengthening the manufacturing readiness 
criteria related to process capability and control of critical 
components and/or interfaces prior to the Milestone C low rate initial 
production decision. However, program offices and contractors should 
continue to have the latitude to jointly agree on the targets and 
specific process control demonstrations required on the pilot 
production line during the Engineering and Manufacturing Development 
to ensure success. 

Recommendation 3: The GAO recommends that the Secretary of Defense 
direct the Office of the Director, Defense Research and Engineering to 
assess the need for analytical models and tools to support MRL 
assessments. 

DOD Response: Concur. The Department will collaborate with government 
services, contractors, and academia to capture knowledge and provide 
improved tools for government and contractor usage in conducting 
assessments of manufacturing readiness as part of systems engineering 
technical reviews and milestone reviews. 

Recommendation 4: The GAO recommends that the Secretary of Defense 
assess the adequacy of the manufacturing workforce knowledge and 
skills base across the military services and defense agencies and 
develop a plan to address current and future workforce gaps. 

DOD Response: Concur. We agree that the production, quality and 
manufacturing (PQM) career field has suffered erosion, as have other 
DoD career fields. The USD (AT&L) Director of Human Capital has 
launched a review of the PQM career field design to identify the 
skills, knowledge and training required at each level of career 
progression in order to develop training courses and evaluate 
progression of anticipated DoD planned new hires. The Department has 
started to implement hiring and retention strategies to mitigate the 
potential loss in experienced, senior-level PQM talent and increase 
the size of the manufacturing workforce. As part of the Secretary's 
growth strategy and other initiatives, the PQM career field is 
projected to grow approximately 1,300 (13%) by FY2015. Each of the 
military services and other DOD components has been actively planning 
and deploying initiatives that support the DOD acquisition workforce 
growth strategy. Components have submitted planning inputs to OSD and 
to the Defense Acquisition Workforce Senior Steering Board, and growth 
is underway.

[12] The three decision points within the DOD acquisition framework 
include: milestone A (entry point for the technology development 
acquisition phase); milestone B (entry point for the engineering and 
manufacturing development period--which is comprised of two phases 
called integrated system design, and system capability and 
manufacturing process demonstration); and milestone C (entry point for 
the production and deployment acquisition phase). DODI 5000.02 (Dec.

Experience Cost and Schedule Problems under DOD's Revised Policy, 
[hyperlink, http://www.gao.gov/products/GAO-06-368] (Washington, D.C.: 
Apr. 13, 2006). 

[14] Major defense acquisition programs are those identified by DOD 
that require total research, development, test, and evaluation (RDT&E) 
expenditures, including all planned increments, of more than $365 
million or procurement expenditures, including all planned increments, 
of more than $2.19 billion in fiscal year 2000 constant dollars. 

[15] In April 9, 2007, the Secretary of the Air Force reported the 
average procurement unit cost increased more than 50 percent above the 
initial baseline estimate and that the majority of the cost growth was 
attributed to a reliability improvement program to deal with the 
missile's reliability problems, addition of the extended range 
variant, and reduction in missile quantities. However, the program 
reported that, even without the quantities associated with the 
extended range variant, the program would have experienced a 
significant breach to the original baseline. 

[16] Automated production processes have been implemented primarily 
for the sensor, and for other limited activities, but have not been 
implemented across the entire program. 

[17] Technical reviews fall under the Systems and Software Engineering 
organization, within the Office of the Secretary of Defense, where 
responsibilities for quality and oversight of defense programs reside. 

[18] The preliminary design review ensures that the system under 
review has a reasonable expectation of satisfying the requirements 
within the currently allocated budget and schedule. The review 
includes evaluation areas and checklist questions. 

[19] The critical design review ensures that the system under review 
has a reasonable expectation of satisfying the requirements of the 
Capability Development Document within the currently allocated budget 
and schedule. This review assesses the final design as captured in 
product specifications for each configuration item in the system and 
ensures that each product specification has been captured in detailed 
design documentation. 

[20] The production readiness review examines a program to determine 
if the design is ready for production and if the prime contractor and 
major subcontractors have accomplished adequate production planning 
without incurring unacceptable risks that will breach thresholds of 
schedule, performance, cost, or other established criteria. The review 
evaluates the full, production-configured system to determine if it 
correctly and completely implements all system requirements. 

[21] An ISO certification against a standard, such as ISO 9000, means 
that an independent external body has audited an organization's 
quality-management system and verified that it conforms to the 
requirements specified in the standard. 

[22] Process controls are the use of statistical methods to monitor, 
track, and reduce the variability of manufacturing processes.
