C-17A Sustainment Performance Metrics Assessment: Repair Source Impact on Sustainment for Future Business Case Analysis Development.

摘要

The C-17A Globemaster III began service on June 14, 1993 and demonstrates some of the highest levels of aircraft availability in the USAF inventory. The sustainment activities responsible for these levels are conducted through a public-private partnership. The Air Force entered this sustainment partnership without the advantage a business case analysis (BCA). In June, 2006, the Department of Defense Inspector General (DoDIG) directed the creation of a BCA for the C-17A program to assess all alternative sustainment strategies, along with recommendations for best-value alternatives. Starting in 2007 and completed in 2009, the BCA provided analysis of three areas for predicting sustainment objective accomplishment: benefits, cost, and risk. While the 2009 BCA encompassed the most detailed assessment of alternatives to- date, it contained shortfalls. Analysis of the benefit metrics showed significant interaction between the chosen metrics resulting in skewed analysis and difficulty discerning between options. The objective of this study was to develop mutually exclusive BCA benefit metrics to assess sustainment strategies, weights to use within a decision analysis framework to better inform future BCAs, and develop business rules to exclude data during transitional phases of sustainment in supporting datasets.
