When does Detailed Design Work typically begin?

• A. Detailed design work
• B. After Critical Design Review
• C. After Conceptual Design
• D. After Acceptance Testing

Answer: (A)

Detailed design work begins once the design has been formally reviewed and deemed mature enough to proceed into production drawings and specifications. This maturity is demonstrated through a Critical Design Review, where interfaces, tolerances, and fabrication details are locked in. After passing this review, engineers can generate the precise drawings, bills of materials, and assembly plans needed for fabrication and integration. Starting the detailed work after Conceptual Design would leave too much uncertainty, while waiting until after Acceptance Testing would come too late to influence the design and would waste resources. This sequencing helps manage risk and ensures manufacturability.
