Life-Cycle Sustainment involves the early planning, development, implementation, and management of a comprehensive, affordable, effective performance driven logistics support strategy. It plays a key role during all phases of the life cycle (See Figure 5.1.1.F1 in the Defense Acquisition Guidebook (DAG)). The goal is to ensure sustainment considerations are integrated into all planning, implementation, management, and oversight activities associated with the acquisition, development, production, fielding, support, and disposal of a system across its life cycle. This includes: [1]

  • Participating in the design process to acquire a highly supportable and sustainable system
  • Providing affordable, reliable, effective support strategies and systems that meet the user’s requirements with optimum materiel availability
  • Developing the appropriate metrics to validate and verify the system engineering design process, and measure the performance of the support strategy/supply chain
  • Providing the user effective systems with the minimal logistics footprint (e.g., the measurable size or “presence” of logistics support, including manpower, required to deploy, sustain, and move a system).
  • Developing more integrated and streamlined acquisition and statutorily complaint logistics support processes
  • Facilitating iterative technology enhancements during the system life cycle
