This evaluation involves examining and testing assembled product components for performance, suitability, or readiness using the available procedures and environment. It is performed as appropriate for different stages of assembly of product components as identified in the product integration sequence and available procedures. The product integration sequence and available procedures may define a more refined integration and evaluation sequence than might be envisioned just by examining the product architecture. For example, if an assembly of product components is composed of four less complex product components, the integration sequence will not necessarily call for the simultaneous integration and evaluation of the four units as one. Rather, the four less complex units may be integrated progressively, one at a time, with an evaluation after each assembly operation prior to realizing the more complex product component that matched the specification in the product architecture. Alternatively, the integration sequence and available procedures could have determined that only a final evaluation was the best one to perform.
