The decision to begin fabrication of production representative prototype systems is based on the output of which design review?

• A. System Design Review
• B. Critical Design Review
• C. Operational Readiness Review
• D. Preliminary Design Review

Answer: (B)

Beginning fabrication of production-representative prototypes rests on having a fully defined, baselined detailed design with all interfaces, manufacturability considerations, and test plans resolved. This level of maturity is achieved at the Critical Design Review, which comes after the Preliminary Design Review and before fabrication. At this point the design is evaluated to ensure it meets all requirements, drawings and specifications are complete, tolerances and interfaces are defined, and producibility and verification plans are in place. Once the design is officially baselined, production can proceed with confidence that late design changes won’t derail timelines or quality. Operational Readiness Review focuses on fielding and operation rather than design maturity. Preliminary Design Review checks feasibility of the chosen concept earlier in the process, and System Design Review assesses broader system aspects at a different stage.
