Life-Cycle Sustainment Plan
The Life-Cycle Sustainment Plan (LCSP) is required by DoD Instruction 5000.02 and documents the Program Manager‘s (PM) and Product Support Manager's (PSM) plan for formulating, implementing and executing the sustainment strategy. The plan is included in the overall Acquisition Strategy of a program and describing the approach and resources necessary to develop and integrate sustainment requirements into the system‘s design, development, Testing & Evaluation, fielding and operations. It also details the development of a product support package (including any support contracts) and how they contribute to the Warfighter‘s mission requirements by achieving and maintaining the Sustainment Sustainment Key Performance Parameters (KPP) and Key System Attributes (KSA). 
The LCSP should address the following areas: 
- The maintenance and support concepts
- How the sustainment metrics will be achieved and sustained throughout the life-cycle
- How sustainment is addressed as an integral part of the program‘s acquisition strategy and system design process
- The assigned responsibilities and management approach for achieving effective and timely acquisition, product support, and availability throughout the life-cycle including the PM role in planning for and executing sustainment
- The funding required and budgeted by year and appropriation for the main sustainment cost categories including operating & support costs
- The plan for identifying and selecting sources of repair or support
- The sustainment risk areas and mitigation plans
- Product support implementation status
- Results and recommendations from DoD Component Independent Logistics Assessments (ILA)
The evolution of the LCSP is detailed below: 
- Pre-Milestone A: The LCSP begins in the Materiel Solution Analysis (MSA) Phase by describing the notional product support and maintenance concepts used to determine the sustainment requirements optimizing readiness outcomes and minimal Life Cycle-Cost (LCC).
- Milestone A: The LCSP evolves from a strategic outline to a management plan describing the sustainment efforts in the system design and acquisition processes to achieve the required performance and sustainment outcomes necessary to ensure required Warfighter capabilities.
- Milestone B: The LCSP evolves into a detailed execution plan for how the product support package is to be designed, acquired, sustained, and how sustainment will be applied, measured, managed, assessed, modified, and reported from system fielding through disposal. The LCSP is submitted with the Acquisition Strategy prior to Milestone B and the Executive Summary is included in the Acquisition Strategy.
- Milestone C: At this point the LCSP describes the content and implementation status of the product support package to achieve the Sustainment KPP/KSAs.
The Program Manager (PM) and Product Support Manager's (PSM) are responsible for the content and preparation of the LCSP but should work with the user, the Product Support Manager, Product Support Integrator(s), and Product Support Providers to document performance and sustainment requirements specifying objective outcomes, resource commitments, and stakeholder responsibilities. 
- Currently the DoD Components use different names to address this requirement, e.g., the Army's Supportability Strategy, the USAF's Life-Cycle Management Plan.
