Definition

During design verification, the detailed design is verified, tested, and refined (if necessary). This phase starts after the detailed design is completed and the complete documentation, including technical drawing, machine control files, and production plans, for the product is finished (Pahl and Beitz 1996).

During this phase prototypes are constructed and tested to verify production processes and product parts. When all tests are passed and design verification ends, the production can be ramped-up, making full use of the production systems, and launch the product.

During the design verification phase, two specific prototypes are defined (Ulrich and Eppinger 2008):
  • Alpha prototype: These prototypes are built with similar parts as intended (e.g., geometry, material), but not necessarily produced in the way the final production will be. Alpha prototypes are used to test whether the product will work as designed.

  • Beta prototype: These...
