Number: RS21195 Title: Evolutionary Acquisitions and Spiral Development in DOD Programs: Policy Issues for Congress Authors: Gary J. Pagliano and Ronald O'Rourke, Foreign Affairs, Defense, and Trade Division Abstract: The Department of Defense (DOD) in 2001 adopted a new approach for developing major weapon systems, called evolutionary acquisition with spiral development (EA/SD), as its preferred standard. EA/SD is intended to make DOD's acquisition system more responsive to rapid changes in military needs. EA/SD poses potentially important challenges for Congress in carrying out its legislative functions, particularly committing to and effectively overseeing DOD weapon acquisition programs.
