Detail Design Approval Basis refers to the approved detail design resulting from which design review?

• A. The approved detail design resulting from the Preliminary Design Review
• B. The approved detail design resulting from the System Verification Review
• C. The approved detail design resulting from the Critical Design Review
• D. The approved detail design resulting from the Operations Readiness Review

Answer: (C)

Detail Design Approval Basis comes from the point where the design is mature enough to be built, tested, and integrated. That level of maturity is reached at the Critical Design Review, where the detailed drawings, interface control documents, bill of materials, tolerances, and verification plans are thoroughly reviewed and baselined as ready for fabrication. The approved detail design at this stage forms the official baseline used for manufacturing and subsequent testing and integration. Why this fits best: a Preliminary Design Review happens earlier to validate an overall approach, not the fully fleshed-out detail design. A System Verification Review checks that the system as built meets requirements, often after development and integration, rather than establishing the fabrication baseline. An Operations Readiness Review assesses whether the program is ready to operate in the field, not whether the design is ready to be manufactured.
