Performance-Based Logistics (PBL), also known as performance-based life-cycle product support or performance-based contracting, is a strategy for cost-effective weapon system support. Rather than contracting for the acquisition of goods and services, the product support manager identifies product support integrator(s) (PSI) to deliver performance outcomes as defined by performance metric(s) for a system or product. The integrator often commits to this performance level at a lower cost, or increased performance at costs similar to those previously achieved under a non-PBL or transactional portfolio of product support arrangements for goods and services. The preferred approach to supporting weapon system logistics. It seeks to deliver product support as an integrated, affordable performance package designed to optimize system readiness. PBL meets performance goals for a weapon system through a support structure based on long-term performance agreements with clear lines of authority and responsibility.〔Defense Acquisition University Acquipedia Article, “Performance Based Logistics”〕 DoD program managers are required to develop and implement performance-based life-cycle support strategies for weapon systems. These strategies should optimize total system availability while minimizing cost and logistics footprint. Trade-off decisions involve cost, useful service, and effectiveness. The selection of the specific performance metrics should be carefully considered and supported by an operationally oriented analysis, taking into account technology maturity, fiscal constraints, and schedule. In implementing performance-based life-cycle product support strategies, the metrics should be appropriate to the scope of product support integrators and providers responsibilities and should be revisited as necessary to ensure they are motivating the desired behaviors across the enterprise.〔Defense Acquisition Guidebook, Section 5.1.1.2〕〔Defense Acquisition Guidebook, Section 5.1.1.3〕 PBL strategies do not mandate that work be contracted to commercial contractors; integrating the best features of the public and private sectors is a key component of the support strategy. Instead of a pre-ordained course of action, Product Managers are directed to implement “sustainment strategies that include the best use of public and private sector capabilities through government/industry partnering initiatives, in accordance with statutory requirements.” 〔DoD Directive 5000.01, The Defense Acquisition System, Enclosure 1, Section E1.1.17 - Performance Based Logistics〕 Many times, employing a PBL strategy has resulted in either increased system performance issues or increased costs. Examples include the C-17 PBL, FIRST, and PBtH. Ideally, the provider profits by controlling constituent elements (PSIs) that are used to generate the performance results. == History == Beginning in the early 1990s, emerging trends towards increases in the costs to support fielded systems and decreases in the general reliability and operational readiness of weapon systems were recognized as issues that could continue if unabated. As a result, a performance-based approach, PBL, was advanced by the U.S. DoD in its annual Quadrennial Defense Review in 2001. Since then, not only has the U.S. DoD adopted the PBL approach, but other countries have adopted this strategy as well. Many programs that have employed it have yielded increased system availability, shorter maintenance cycles, and/or reduced costs. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Performance-based logistics」の詳細全文を読む スポンサード リンク
