Evolutionary Acquisition

This monograph presents findings of a RAND Project AIR FORCE research project documenting lessons learned by the U.S. Air Force (USAF) and other Department of Defense (DoD) cost analysis and acquisition community members from the implementation of evolutionary acquisition (EA)strategies for major Air Force defense space acquisition programs. In May 2003, DoD mandated EA strategies relying on spiral development as the preferred approach to satisfying operational needs.
