Using the prototypes that were developed the testing and validation is used to measure the performance of the solution. It can include user testing, benchmarking, functionality testing, failure mode analysis, or anything that is deemed appropriate. The prototype should be evaluated against the requirements and constraints developed during needs assessment.
