ABSTRACT
Purpose The primary purpose of stage 4 is for the architecture design team to evaluate the initial architectural design, or reevaluate the refined design after architectural evaluation and experimentation.
Preconditions Before undertaking stage 4 the architecture design must be sufficiently complete to facilitate the design evaluation. At a minimum, the architecture design must be designed and documented in preliminary fashion with representation from the three primary perspectives. In addition to drawings, there must be sufficient prose to describe the design and its rationale.
