Fast Facts

The National Nuclear Security Administration is spending billions on programs to modernize the nation's nuclear weapons stockpile.

Managing expensive, complex programs is challenging. Industry leaders use portfolio management to prioritize resources for programs that best achieve an organization's strategic goals.

NNSA says that its Weapons Activities work is a portfolio and has partially implemented leading practices. However, the agency hasn't clearly defined this portfolio—i.e., fully documented what's included in the portfolio and how it links to the agency's mission and strategic objectives. We recommended that it do so.

What GAO Found

The National Nuclear Security Administration (NNSA) has partially implemented selected leading practices to manage the work necessary to maintain and modernize the nation's nuclear weapons stockpile. GAO found that NNSA is in the early stages of initiating its portfolio management processes and has partially implemented leading practices, such as establishing a clearly defined portfolio of work. For example, NNSA officials stated that its Weapons Activities appropriations account is a portfolio of work. However, NNSA has not developed clearly defined and appropriately empowered governance roles, such as a portfolio manager, for its Weapons Activities portfolio. As NNSA continues to develop its approach to portfolio management, establishing a portfolio management framework—consistent with selected leading practices—may allow NNSA to fully implement all leading practices, better define how program offices will pursue strategic stockpile modernization objectives, and optimize portfolio performance in the event that budget trade-offs become necessary.

NNSA's offices have undertaken four separate efforts to identify and assess the capabilities needed across the nuclear security enterprise to meet its stockpile maintenance and modernization mission, but NNSA has not developed a comprehensive or complete capability assessment that could support its portfolio management approach (see fig.). NNSA undertook three of these four independent efforts to identify and assess capabilities in response to different legislative direction and did not incorporate information on all elements of a capability (knowledge, human capital, and infrastructure) in any of the individual efforts. Working across the agency to conduct a comprehensive, complete capability assessment would provide NNSA with a portfolio-level view of the enterprise's capabilities and needs, allowing for planning that considers interdependencies that have been missed in the past when planning focused on individual programs or projects.

Why GAO Did This Study

NNSA is simultaneously modernizing the nation's nuclear weapons stockpile and the infrastructure on which weapons research and production programs depend. These efforts include multi-billion-dollar defense programs and projects that provide the capabilities needed for maintenance and modernization programs. Congress previously directed NNSA to identify its needed capabilities.

The Senate report accompanying the National Defense Authorization Act for Fiscal Year 2020 includes a provision for GAO to review NNSA's approach to managing its defense programs and to identifying capabilities. This report examines the extent to which NNSA (1) used selected portfolio management leading practices to manage its maintenance and modernization programs and projects and (2) developed a comprehensive and complete capability assessment to support portfolio management.

GAO reviewed NNSA documentation related to portfolio management and capabilities and compared it with leading practices and legislative requirements. GAO also interviewed NNSA officials from six agency offices.

Recommendations

GAO is making two recommendations: NNSA should (1) establish a portfolio management framework and (2) develop a comprehensive and complete capability assessment. NNSA concurred in principle with the recommendations and stated that they have addressed them. GAO believes that NNSA needs to take additional actions to fully address the recommendations.

Recommendations for Executive Action

Agency Affected Recommendation Status
National Nuclear Security Administration 1. The NNSA Administrator should establish an enterprise-wide portfolio management framework. The framework should define the portfolio of weapons stockpile and infrastructure maintenance and modernization programs and its governance roles, as well as include portfolio-level selection criteria, prioritization criteria, and performance metrics. (Recommendation 1)
Open
NNSA agreed in principle with our recommendation to establish an enterprise-wide portfolio management framework. However, NNSA stated that it considers the recommendation to be closed--that sufficient action has already been taken to address the recommendation--based on existing documents and processes. We reviewed NNSA's existing documents and processes as part of our review and disagree that they fully address our recommendation. In its comments on our recommendation, NNSA recognized that it is in the early stages of implementing portfolio management processes for its Weapons Activities portfolio of work and that the leading practices we identified can be useful in developing a portfolio management approach. We are encouraged that NNSA recognizes the usefulness of incorporating portfolio management leading practices into its management of the Weapons Activities portfolio. Our recommendation to establish a framework includes leading practices that are broad and flexible enough for NNSA to apply to managing its weapons stockpile and infrastructure maintenance and modernization efforts. An established portfolio management framework--a cohesive, strategic document that clearly defines the portfolio and how to manage it and prioritize its components--would provide NNSA with a more structured and defensible approach to managing the billions of dollars of work that comprise the Weapons Activities portfolio. We will continue to review NNSA's progress to address this recommendation.
National Nuclear Security Administration 2. The NNSA Administrator should work across the agency's offices that contribute to achieving the goals and objectives of the stockpile maintenance and modernization portfolio to develop a comprehensive capability assessment that incorporates the three elements of capabilities (knowledge, human capital, and infrastructure). (Recommendation 2)
Open
NNSA agreed in principle with our recommendation to work across offices to develop a comprehensive and complete capability assessment. However, NNSA stated that it considers the recommendation to be closed--that sufficient action has already been taken to address the recommendation--based on existing documents and processes. We reviewed NNSA's existing documents and processes as part of our review and disagree that they fully address our recommendation. In its comments on our recommendation, NNSA specifically referenced the Stockpile Stewardship and Management Plan--one of its four efforts to identify and assess capabilities needed for its nuclear weapons stockpile maintenance and modernization mission. We found that NNSA's effort to identify and assess capabilities in the Stockpile Stewardship and Management Plan was incomplete in that it did not fully consider all three elements of a capability (knowledge, human capital, and infrastructure). While we are encouraged that NNSA stated it will refine these assessments in the future versions of the Stockpile Stewardship and Management Plan, we continue to believe that NNSA should work to develop a single comprehensive and complete capability assessment rather than maintain and coordinate four separate efforts. We believe that this would better support NNSA's strategic management of the Weapons Activities portfolio and better position NNSA to identify and assess, plan for, and address capability challenges for the enterprise in advance rather than react to them as they emerge. NNSA could include this single comprehensive and complete capability assessment in future iterations of its Stockpile Stewardship and Management Plan. We will continue to review NNSA's progress to address this recommendation.
