Welcome to the Parts Management Knowledge Sharing Community !

The Parts Management Knowledge Sharing Portal (PMKSP) is designed to provide an easily accessible knowledge base for parts management related information and a forum for parts management related discussions.

The Defense Parts Management Program

The purpose of the DoD Parts Management Program is to establish parts management best practices across DoD in order to increase weapon system availability and reduce total ownership costs.  Selecting preferred parts during weapon system design drives positive outcomes throughout the life cycle of a system.  DoDM 4120.24 states, "Program offices must apply standardization processes to improve parts commonality," and, "should ensure that a parts management process is used to reduce the proliferation of parts and associated documentation." To accomplish these goals we:            

  • Review and revise DoD parts management related policy and guidance

  • Assess the effectiveness of DoD parts management activities across DoD

  • Research, identify, and promote parts management best practices across DoD and Industry

  • Prepare and Publish SD-19 – Parts Management Guide

  • Promote Parts Management education and engagement

  • Establish and pursue DoD – wide Parts Management Strategic Objectives

What is Parts Management?

This process determines the optimum parts while considering all the factors that may affect program outcomes. Parts are the building blocks from which systems are created and greatly impact hardware dependability and readiness. Since the reliability, maintainability, and supportability of the end item are dependent upon these building blocks, applying effective parts management is very important. Key benefits of parts management include reducing the proliferation of parts, enhancing system supportability and reducing total ownership costs.

Benefits of Parts Management: Implementing parts management early in the engineering and design phase of a system has multiple benefits.

  • Cost Savings and Cost Avoidance. Robust parts management during design and production helps save design and life-cycle costs of equipment by promoting the application of commonly used or preferred parts.
  • Enhanced Logistics Readiness and Interoperability. Using common components simplifies logistics support, enhances substitutability and translates to savings in procuring, testing, warehousing, and transporting parts.
  • Reduced Acquisition Lead-Time. When preferred parts are used, the government and industry avoid the expenses and delays of designing and developing parts.
  • Increased Supportability and Safety of Systems and Equipment. Preferred parts reduce risk and improve the chances that equipment will perform reliably and reducing mission failure or loss of life.
  • Reliability and maintainability engineering. Ensuring that the parts selected meet contractual requirements and proper design results in enhanced reliability, availability and maintainability.

Parts Management, Systems Engineering, and the Acquisition Process:  Parts management is an essential element of systems engineering during the early design phase of the acquisition process.  It is fundamental to achieving many systems engineering and manufacturing objectives, it influences cost, schedule, and performance, and impacts acquisition technical reviews including System Requirements Review, System Functional Review, Preliminary Design Review, Critical Design Review and Production Readiness Review.  Parts Management continues to be an essential element of the acquisition process through the operations and support phase as systems are sustained.

Parts & Material Management Working Group: The Parts & Material Management Working Group (P&MM WG) provides a forum for promoting, shaping, and coordinating government and industry approaches to effective parts management and Diminishing Manufacturing Sources and Material Shortages (DMSMS). The working group, which meets twice a year, fosters continuous improvement in both Defense and Industry-related parts management processes and practices. At each meeting Working Group members are asked to present parts management and DMSMS activities being undertaken in their home organizations with an eye toward identifying cross-cutting approaches that can be applied across Services and DoD.
