The approved detail design that results from which review serves as the basis for deciding to begin fabrication of production-representative prototype systems?

• A. System Requirements Review (SRR)
• B. Critical Design Review (CDR)
• C. Preliminary Design Review (PDR)
• D. Functional Configuration Audit (FCA)

Answer: (B)

Approving the detailed design and baselining it is what lets fabrication begin. At this stage the design is complete and stable: all drawings, part specifications, interfaces, and verification methods are defined, vetted, and ready to be produced. This approved, baselined design becomes the reference for building production-representative prototypes, ensuring consistency with requirements and enabling controlled changes only through formal processes. Earlier reviews serve different purposes: a requirements-focused review confirms what the system must do and that a plan exists to meet it; a preliminary design review verifies a feasible approach that could satisfy the requirements; a functional configuration audit checks that final products match the approved design after fabrication. The critical design review is the milestone that hands over to fabrication by establishing the detailed design as the baseline.
