Defense Logistics: Improved Analysis and Cost Data Needed to Evaluate the Cost-Effectiveness of Performance Based Logistics

摘要

In 2001, the Department of Defense (DOD) identified performance based logistics (PBL) as the preferred weapon system support strategy. Within DOD, PBL is the purchase of performance outcomes, such as system availability, rather than the purchase of individual elements of logistics support--such as parts, repairs, and engineering support. Although PBL initially arose from efforts to reduce support costs, questions have arisen about whether PBL has reduced support costs as originally intended. GAO was asked to evaluate the extent to which DOD has used business case analyses to guide decisions related to PBL arrangements and the impact PBL arrangements have had on weapon system support costs. In conducting the review, GAO analyzed the implementation of PBL arrangements for 29 weapon system programs. GAO also looked at the use and characteristics of performance-based contracting in the United Kingdom's Ministry of Defence. Although DOD's guidance recommends that business case analyses be used to guide decision making regarding the implementation of PBL to provide weapon system support, the services are not consistent in their use of such analyses. About half of the DOD program offices responsible for the 29 PBL arrangements GAO reviewed either did not use a business case analysis or could not provide documentation for significant parts of their analyses.
