Touchpoints between the SCEA Cost Estimating Body of Knowledge (CEBoK®) and the Program Management Institute (PMI) Body of Knowledge (PMBoK)

Informational Sessions



The General Accounting Office (GAO), in its publication of the “GAO Cost Estimating and Assessment Guide” in May of 2009, focuses extensively on the importance of Cost Estimation and its contribution to overall project success. While this publication offers specific technical examples of cost estimation and analysis capability, e.g. pre-Program approval cost estimates/baselines, Affordability Analysis, et al, there is less focus on how these technical examples “fit” into the larger Project Management context.

The Project Management Institute(C) (PMI) PM Framework is constructed around five Process Groups that intersect with nine Knowledge Areas. There are specific intersections on this matrix within which Cost Estimation and Analysis play significant roles; this paper will detail these roles, while positing opportunities for skilled Cost Estimator/Analysts to utilize their CEBoK-based technical expertise in support of a more robust PMBoK-based Program Management focus.

Cost Estimator/Analysts that have an understanding of these roles will allow for the opportunity to maximize added value to Programs and Projects. Given the increase of uncertainty in the Federal Budget and the implied challenge to “do more with less,” a greater understanding of Program Management can be potentially leveraged by Cost Estimator/Analysts as a discriminator to provide additional career-broadening opportunities.
