There is significant anecdotal evidence that Performance-Based Logistics (PBL) contracts are effective; however, studies from the GAO and others highlight the pressing need to improve the management of existing PBL programs and to develop more realistic business cases to assess the costs, benefits, and risks. A recent report from the Lexington Institute and a quantitative study from the Wharton School are helping to answer the question: Do PBL contracts provide value to both suppliers and customers?
The report from the Lexington Institute titled "Performance-Based Logistics: A Primer for the New Administration," describes the challenge that the Obama administration faces in decreasing defense spending while maintaining a strong military.
The Institute, who "strives to find non-governmental, market-based solutions to public policy programs," states that "the administration can have a significant, early impact on national security by directing the Department of Defense to move forward aggressively on PBL."
Since the Department of Defense began implementing PBL in 2001 through Performance-Based Agreements (PBA's), the services have seen a marked increase in the availability of equipment and systems to our military in combat, and a study of 23 PBA's showed an average savings of $21 million.
PBL programs from Boeing IDS and Lockheed Martin Aeronautics, who have implemented MCA's PBL solution across several platforms, are noted as dramatic success stories, but PBL contracts have been implemented across only a small percentage of the hundreds of major weapon systems managed by DOD. The report makes an argument that the DOD needs to redouble its effort to institutionalize PBL in its logistics and sustainment activities by clearing up lingering uncertainties about PBL effectiveness and defining and documenting the business case.
To better understand the case for PBL, MCA founder Morris Cohen, and his colleagues at the Wharton School have been doing extensive research on PBL to determine effectiveness and quantify its benefits. In a recent study performed with a major aerospace manufacturer the team looked at 5 years of reliability data based on MTBR (Mean Time Between Removal) in contracts that were executed as either Time & Material (T&M) contracts or Performance-Based Contracts (PBC). After isolating the impact of contract type from other factors such as contract choice and type of product, the results showed with high confidence that there is a significant correlation between choice of a PBC contract and an increase of product reliability of 10% to 25% in comparison to T&M contracts. Analysis of the data shows that, all else being equal, PBC increases the MTBR of a product by 790 flying hours in the five-year observation period.
The study is significant in that it's the first to test and validate the reliability improvement hypothesis for performance-based contracting based on transactional data, and it makes a step in closing the gap between theoretical modeling and empirical evidence.
MCA remains committed to continuing to provide tools to improve the effectiveness of PBL contracts, and we look forward to hearing from our readers on their experiences with PBL contracts and what could make them more effective.
