09 When FTA undertakes a risk assessment, how does it determine whether the sponsor’s budget and schedule are reasonable?
FTA has continued to refine the technical methods and adjust the probability thresholds it uses to undertake the risk assessment based on historic data from previous projects. When determining the reasonableness of a project sponsor’s cost and schedule, FTA reviews the estimates to determine whether they include reasonable assumptions or whether adjustments need to be made. FTA then examines risks related to the project to determine the appropriate level of contingency needed. FTA will use a 65% probability threshold to determine reasonableness of the cost and schedule estimates.
