On Sept. 8, 1982, Pres. Ronald Reagan signed into law the DoD Authorization Act which included what has come to be known as the Nunn-McCurdy (NM) Act. The NM Act requires DoD to report to Congress whenever a major defense acquisition program experiences cost overruns that exceed certain thresholds. Contents of this report: (1) Intro.; (2) Background: What is a NM Breach?: NM Thresholds; NM Timelines; Conseq. of a Critical NM Breach; Effectiveness of the NM Act: NM as a Reporting Mechanism; NM as a Mechanism for Controlling Cost Growth; (3) Issues for Congress: NM as a Reporting and Mgmt. Tool; Shortening the NM Timeline; Managing Admin. Breaches; Applying NM-Type Reporting Requirements to O&S Costs. Illus.

Congressional concern with cost overruns, or breaches, in several major defense acquisition programs led the authors, in a partnership with the Performance Assessments and Root Cause Analysis Office in the Office of the Secretary of Defense, Acquisition, Technology, and Logistics, to investigate root causes by examining program reviews, analyzing data, participating in contractor briefings, and holding meetings with diverse stakeholders.

NASA's Science Mission Directorate (SMD) currently operates over five dozen missions, with approximately two dozen additional missions in development. These missions span the scientific fields associated with SMD's four divisionsâ€"Astrophysics, Earth Science, Heliophysics, and Planetary Sciences. Because a single mission can consist of multiple spacecraft, NASA-SMD is responsible for nearly 100 operational spacecraft. The most high profile of these are the large strategic missions, often referred to as "flagships." Large strategic missions are essential to maintaining the global leadership of the United States in space exploration and in science because only the United States has the budget, technology, and trained personnel in multiple scientific fields to conduct missions that attract a range of international partners. This report examines the role of large, strategic missions within a balanced program across NASA-SMD space and Earth sciences programs. It considers the role and scientific productivity of such missions in advancing science, technology and the long-term health of the field, and provides guidance that NASA can use to help set the priority of larger missions within a properly balanced program containing a range of mission classes.

For nearly 30 years, the statutory provision, known as Nunn-McCurdy (NM), has been an oversight tool for Congress to hold the DoD accountable for cost growth on major defense programs. A NM breach occurs when a program's unit cost exceeds certain thresholds. When that happens, DoD must notify Congress of the breach. There are a number of statutory provisions that help implement cost growth reporting under NM. Referring to these statutory provisions as the NM process, this report examines trends in NM breaches and factors that may be responsible for these trends. It also discusses changes DoD is making or proposing to make to the NM process. Charts and tables. This is a print on demand report.
