Which design activity typically occurs after the Preliminary Design Review?

• A. System Requirements Review
• B. Conceptual Design
• C. Manufacturing Readiness Review
• D. Detailed design work

Answer: (D)

Understanding the sequence of design reviews and what each stage produces is tested. After a Preliminary Design Review, the design has been shown to be feasible and to meet requirements at a high level, so the project proceeds to detailed design work. This involves finalizing components, refining interfaces, producing precise drawings and specifications, setting tolerances, and laying out fabrication and integration plans. This detailed design output is what’s needed to prepare for the Critical Design Review and actual production. The other options fit earlier or later stages: defining requirements is done before the PDR, conceptual design happens earlier in the cycle, and a manufacturing readiness review occurs once the design is mature enough to consider production.
