Which design document serves as the basis to begin fabrication of production representative prototype systems?

Which design document serves as the basis to begin fabrication of production representative prototype systems?

• A. Preliminary Design Review
• B. Approved detail design
• C. Conceptual Design
• D. Final Deployment Plan

Answer: (B)

The key idea is that fabrication begins when the design is fixed and ready for production. The approved detail design contains the final, baselined specifications needed to actually build, with exact geometry, chosen materials, tolerances, interfaces, and manufacturing processes. Having this level of detail approved ensures that production-representative prototypes are built to reflect the intended production configuration, enabling accurate verification and validation. Earlier stages—conceptual and preliminary designs—outline concepts and architecture but do not lock down the specifics required for manufacturing. A deployment plan focuses on field use and deployment logistics, not on how to fabricate the prototype. So, the document that serves as the basis to begin fabrication is the approved detail design.
