In which phase of the Defense Acquisition System is competitive prototyping usually required?

• A. Production & Deployment
• B. Engineering & Manufacturing Development
• C. Materials & Solutions Analysis
• D. Technology Maturation & Risk Reduction

Answer: (D)

Competitive prototyping is used to mature technologies and compare different design approaches by building and testing early, working prototypes from multiple vendors. This hands-on exploration helps reveal technical risks, performance gaps, and cost and schedule implications before committing to a single solution.

In the Defense Acquisition System, that kind of activity belongs in the Technology Maturation & Risk Reduction phase. The goal here is to reduce risk and prove that the chosen technology path can meet requirements, often through competitive prototypes that demonstrate different approaches. The insights gained feed the decision on which solution to pursue into Engineering & Manufacturing Development.

Once you move to Production & Deployment, the focus shifts to manufacturing, integration, and fielding the chosen system, not on running new competitive prototypes. Earlier phases may involve analysis and initial feasibility, but competitive prototyping is the step used to inform the selection of a single path during the maturation and risk-reduction stage.
