ABSTRACT
The results to be achieved by the design and development process are those that the organization has deemed necessary to accomplish its goals. The purpose of the review is to determine whether the proposed design solution is the most practical and cost-effective way of meeting the requirements and should continue or should be changed before proceeding to the next phase. The input data for the review should be distributed and examined by the review team well in advance of the time when a decision on the design must be made. The review team should have a collective competency greater than that of the designer of the design being reviewed and possess sufficient practical experience to provide advance warning of potential problems with implementing the design. Service design validation is often only possible after service transition during initial trials either with real customers or employees performing the role of customers.
