This briefing discusses a paper comparing two approaches to making choices among alternative systems in the major defense acquisition process. The existing process is characterized as the Decision Science (DS) approach while the alternative is termed the Economic Evaluation of Alternatives (EEoA) approach. The discussion points out that the EEoA approach, as presented, has drawbacks similar to those pointed out in the paper for the DS approach. The discussion also notes that vendor behavior under the EEoA approach may be far from optimal from the government’s point of view.
