PEO GCS requested AMSAA to conduct a verification and validation V and V of the Whole System Trade Analysis Tool WSTAT. In the early stages of the V and V for development risk, it was discovered that the original risk rating and methodology did not actually represent development risk, because consequences were not considered only likelihood. As a result, an appropriate development risk methodology needed to be created for the intended WSTAT applications. In addition to incorporating consequence into the risk methodology, AMSAA created a methodology for the technology distributions, considered criticality of technologies, developed a closed form algorithm, and created a risk rating approach. The purpose of this report is to document how development risk was created for WSTAT.
