AFCAA Cost Risk and Uncertainty Analysis Metrics Manual
The Cost Risk and Uncertainty Handbook (CRUH), published by the Air Force Cost Analysis Agency (AFCAA) in July 2007, is a reference for approved methods, practices, and reporting requirements needed to produce a realistic, defendable cost uncertainty analysis. CRUH addresses the question “how to do it”. CRUAMM provides guidance on “what to base it on” – that is, it provides data and data-driven uncertainty distributions for potential use in your cost model or for use as cross-checks. This paper will present a status on development of this supplement to the AFCAA CRUH.
Choosing the right uncertainty distributions for your cost risk analysis is critical. The purpose of the CRUAMM is to provide the analyst a “place to start” and a source of distributions based upon data-driven analysis. CRUH provided broad, expert opinion suitable for the most generic of analysis. CRUAMM is designed to provide commodity specific guidance at various levels within the commodity WBS, CRUAMM guidance introduces the principle of “orders of dispersion”. Uncertainty is quantified by measuring dispersion in observed data sets at different levels of detail. In the process, a custom curve-fitting tool was developed to facilitate analysis of hundreds of data sets to generate the recommended distribution and the parameters that will become the uncertainty model inputs.
This paper summarizes the 17 Key Risk areas discussed in the CRUAMM, the data collected to date, the analytical curve-fitting framework, emerging results, how to make use of it in a Crystal Ball, @Risk or ACEIT model and the path forward.
