Coast Guard: Actions Needed to Ensure Investments in Key Data System Meet Mission and User Needs
Fast Facts
The Coast Guard tracks and supports its activities with its Marine Information for Safety and Law Enforcement data system. It contains information on over 700,000 vessels and more. Earlier efforts to upgrade the system did not deliver all planned improvements, such as an ability to reduce duplicate records.
Problems persist. For example, users told us duplicate entries created uncertainty on whether vessels or their operators had earlier safety violations or warranted inspection. We also identified data errors and missing records.
We made 4 recommendations, including that the Coast Guard address the causes of system data issues.

What GAO Found
The U.S. Coast Guard's (Coast Guard) Marine Information for Safety and Law Enforcement (MISLE) system is generally able to support agency operations by tracking and aggregating mission activity data, such as commercial vessel inspection results. But the system has some capability gaps, and MISLE users GAO spoke to described numerous challenges with the system. For example, they reported:
challenges using MISLE due to duplicate or incomplete records in the system, which can affect the ability of personnel to conduct activities such as vessel inspections. Users told GAO that duplicate or incomplete records can create a risk that Coast Guard personnel may not have full vessel histories when inspecting vessels to resolve prior safety deficiencies; and
being unable to complete work in MISLE while conducting operational activities, since users can only access the system from a workstation connected to the Coast Guard network. Field personnel told GAO it can require rework when they return to their workstations to enter information into MISLE from paper records.
MISLE system managers stated they are aware of these challenges, have begun to address some of them, and agree that MISLE requires further investments to meet user needs.
The Coast Guard has policies, procedures, and training mechanisms to help ensure reliable data; however, GAO's analysis identified multiple data issues, including data errors, incomplete or missing records, and inconsistent data entry. For example, about 20 percent of the fiscal year 2018 records of search and rescue operations showed a negative response time, which Coast Guard officials attributed to data entry errors. The Coast Guard has not assessed the causes of such data errors, and its recent efforts to address certain data issues do not include plans for such an assessment. Such an assessment could help the Coast Guard identify how to ensure more reliable MISLE data.
The Coast Guard has taken steps to update MISLE since its 2001 release; however, it has not followed its own processes to manage subsequent investments. In its most recent upgrade to MISLE, which began in 2008, the Coast Guard did not follow key systems development processes nor deliver some planned functionalities, such as the ability to remediate duplicate vessel records and input data in mobile capacities. The Coast Guard has initiated further efforts to obtain or develop undelivered functionality since the release of the upgraded system in 2015. However, in its fiscal year 2019 operational analysis of MISLE, the Coast Guard identified additional major system deficiencies and user dissatisfaction that it reported require consideration as it pursues system enhancements. Yet, the agency has not taken steps to assess mission needs across the system. By developing an updated mission needs statement for MISLE as a whole, and by identifying and analyzing alternatives to objectively select solutions in accordance with departmental systems engineering guidance, the Coast Guard would be better positioned to address user needs and to more efficiently manage its various investments to improve MISLE.
Why GAO Did This Study
The Coast Guard, within the Department of Homeland Security (DHS), is the principal federal agency responsible for maritime safety and security. The Coast Guard maintains and uses MISLE—a data system that tracks and reports results data for nearly all Coast Guard missions.
GAO was asked to review the status of MISLE and efforts to update it. This report examines (1) the extent to which MISLE supports Coast Guard operations and decision-making; (2) the extent to which the Coast Guard has policies, procedures, and training to ensure reliable MISLE data; and (3) Coast Guard efforts to enhance, upgrade, or replace MISLE since 2008. GAO reviewed Coast Guard plans and performance documents, policies and procedures related to MISLE data entry; select performance data for four missions from fiscal years 2014 through 2018, the most recent data available; and Coast Guard and DHS systems engineering life cycle and acquisition frameworks. GAO also interviewed Coast Guard field and headquarters MISLE users.
Recommendations
GAO is making four recommendations, including that the Coast Guard (1) assess and address the causes of data errors and inconsistent data entries, (2) develop a mission needs statement, and (3) identify and analyze alternatives to select solutions to meet mission needs. The Coast Guard concurred with all recommendations and said it plans to replace MISLE.
Recommendations for Executive Action
| Agency Affected | Recommendation | Status |
|---|---|---|
| United States Coast Guard | The Commandant of the Coast Guard should ensure that the Deputy Commandant for Mission Support assesses and addresses the causes of data errors and inconsistent entries in MISLE as identified by program offices and MISLE users, including reviewing MISLE training and data validation processes. (Recommendation 1) |
The Department of Homeland Security concurred with this recommendation and said that it will assess the data errors and inconsistencies reported by program offices and users to address the cause of both in the short-term, or as a long-term strategy for correction. In January 2021, the Coast Guard reported it had completed a review of data errors and inconsistencies reported by program offices. Since then, the Coast Guard has made minor user interface enhancements and has continued to address data quality through training provide to MISLE users responsible for entering and validating case information into the MISLE database. In addition, the Coast Guard initiated a project in MISLE to merge duplicate records, such as vessels and facilitates, which it called the MISLE Merge project. As of March 2025, the Coast Guard has revised its approach to the Merge project because it determined that its initial, fully automated approach was too complex to implement. The new approach focuses on simplifying the process through which Coast Guard MISLE users manually merge duplicate records. According to the Coast Guard, it expects to complete the project in the fourth quarter of fiscal year 2025. We are monitoring Coast Guard's progress on the Merge initiative and plan to follow up near the end of fiscal year 2025 for an update.

| United States Coast Guard | The Commandant of the Coast Guard should ensure that the Deputy Commandant for Mission Support uses the results of its 2019 Standardization Team assessment of command centers to develop a plan for improving the consistency and accuracy of MISLE data identified in its report. (Recommendation 2) |
The Department of Homeland Security concurred with this recommendation and said that MISLE program managers are reviewing the standardization team's assessment and recommendations for MISLE improvements. As of March 2025, the agency will address the issue through two technology improvement projects. In the short term, Coast Guard officials said that the agency will make changes to the MISLE system to simplify the process through which users can merge duplicate records, which officials expected to complete in the fourth quarter of fiscal year 2025. In the long term, Coast Guard officials said that the agency is developing a solution to replace MISLE entirely. The Coast Guard is in the process of selecting a technical solution for the MISLE replacement and said that it expects to complete an analysis of alternatives by November 2025. We will follow up with Coast Guard near the end of fiscal year 2025 to obtain an update on these short- and long-term solutions.

| United States Coast Guard | The Commandant of the Coast Guard should ensure that the Deputy Commandant for Mission Support and the Deputy Commandant for Operations use the processes outlined in the SELC to identify needed enhancements across the MISLE system by developing an updated mission needs statement. (Recommendation 3) |
In July 2020, we reported that the Coast Guard had not followed its own processes for managing planned enhancements to the Marine Information for Safety and Law Enforcement (MISLE) information system. Such processes included following the Department of Homeland Security's (DHS) Systems Engineering Life Cycle (SELC). As such, we recommended that the Coast Guard use the processes outlined in the SELC to identify needed enhancements across the MISLE system by developing an updated mission needs statement. The Department of Homeland Security concurred with this recommendation and determined in fiscal year 2020 that MISLE needed to be replaced. In December 2023, the Coast Guard issued a finalized mission needs statement for its planned case management system. The mission needs statement outlined how the Coast Guards' planned case management system will provide the agency with processes, tools, and information technology solutions to support its statutory missions. This includes addressing the capability gaps the Coast Guard described in its April 2022 capability analysis report. These actions meet the intent of the recommendation to follow its own processes by identifying capability gaps and mission needs to articulate the resources necessary to acquire or develop new information technology functionalities. As such, this recommendation is closed as implemented.

| United States Coast Guard | The Commandant of the Coast Guard should ensure that the Deputy Commandant for Mission Support and the Deputy Commandant for Operations use the processes outlined in the SELC to identify and analyze alternatives, and objectively select the preferred solution for MISLE to meet approved mission needs. (Recommendation 4) |
The Coast Guard concurred with this recommendation and determined in May 2020 that MISLE needs to be replaced. In January 2021, the Coast Guard said that it had established an integrated product team to analyze and document the capability gaps, mission needs, and operational requirements for a case management system to replace MISLE. In December 2023, the Coast Guard completed a mission needs statement, which outlined how the Coast Guard's planned case management system will provide the agency with processes, tools, and information technology solutions to support its statutory missions. As of March 2025, the Coast Guard stated that it had completed a preliminary concept of operations for the new case management system. The Coast Guard also stated that it planned to incorporate into the preliminary concept of operations an analysis of alternatives to determine the specific technical solution for the planned case management system to meet its mission needs. The Coast Guard said that it expects to complete its analysis of alternatives for the MISLE replacement in November 2025. We are monitoring Coast Guard's progress and plan to follow up with the Coast Guard at the end of fiscal year 2025 for an update on the development of the analysis of alternatives.
