Nuclear Security Enterprise: NNSA Should Use Portfolio Management Leading Practices to Support Modernization Efforts, Report to the Committee on Armed Services, U.S. Senate [open pdf - 3MB]
From the Highlights: "NNSA [National Nuclear Security Administration] 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 [Government Accountability Office] 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."
