Over the past few years as budgets have become tighter, government agencies have been trying to do more science and research with less resources. As a result, the National Aeronautics and Space Administration (NASA)’s International Space Station ( ISS) Program employs cost estimation as a function of project management in order to make better decisions. The cost estimators and project controls professionals, through the use of parametric tools, have been able to execute effective project controls for various customers, including the program manager, project engineers, and the procurement office. This presentation will exhibit how the various commercial off the shelf tools such as PRICE, the SEER suite, and Primavera are being used effectively to predict cost and schedule outcomes including some of the tactical approaches taken in using the parametrics. Specifically, schedule analysis performed using primavera/pertmaster, applying this to a cost estimates built using PRICE and SEER, and comparing estimates throughout the project lifecycle against the budgets, spend plans, and actual costs.
