## Highlights

GAO has previously reported that requirements changes are factors in poor cost and schedule outcomes on Department of Defense (DOD) weapon programs. In 2007, DOD introduced Configuration Steering Boards (CSBs) to review requirement and configuration changes that could adversely affect programs. In 2008, Congress made annual CSB meetings a requirement for all of the military departments' major defense acquisition programs. In response to the Senate report accompanying the bill for the Ike Skelton National Defense Authorization Act for Fiscal Year 2011, GAO assessed (1) the extent to which DOD has complied with the statutory requirements for CSBs, and (2) the extent to which CSBs have been effective in controlling requirements and mitigating cost and schedule risks. To conduct this work, GAO surveyed DOD's major defense acquisition programs, reviewed CSB documentation, and interviewed relevant military service and program officials.
