What is Parts Management?
The Defense Parts Management Program is an integrated effort to streamline the selection of preferred or commonly used parts during the design of weapon systems and equipment under an overarching Systems Engineering framework. 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.
DoD Procedures and Guidance for Parts Management
- Mandatory Standardization Considerations. DoDM 4120.24, Defense Standardization Program Procedures, Enclosure 4, paragraph 2.c.,dated September 24, 2014, addresses parts management as a mandatory standardization consideration, as follows:
"Parts Management. Program offices must apply standardization processes to improve parts commonality… Program offices should ensure that a parts management process is used to reduce the proliferation of parts and associated documentation and promote the use of parts with acceptable performance, quality, and reliability, as specified in MIL-STD-3018. Total ownership cost analysis must also be applied in the selection of parts for the program."
- The Defense Acquisition Guidebook (DAG) addresses Parts Management in Chapter 3, Systems Engineering, and Chapter 4, Life Cycle Logistics.
- MIL-STD-3018, Parts Management provides requirements for the implementation of an effective parts management program, supports acquisition strategies and systems engineering practices, and provides performance-based processes and practices intended to be adapted to individual program needs. When used in conjunction with SD-19, “Parts Management Guide,” MIL-STD-3018 outlines parts management needs in contracts and parts management processes for prime contractors and subcontractors. MIL-STD-3018 requires a parts management plan. See DI-SDMP-81748, Parts Management Plan.
The Parts Standardization and Management Working Group (PMWG)
In April 2018, the Parts Standardization Management Committee (PSMC) was renamed the Parts Management Working Group (PMWG). The Defense Standardization Program Office (DSPO) chartered the PMWG (formerly the PSMC) in 2006 to advise DSPO in the development of parts management policy, procedures and guidance. The PMWG’s goal is to establish parts management best practices across DoD to increase weapon system operational availability and reduce total ownership costs. The PMWG website provides more information on the structure of the committee, current focus areas, and the schedule for semi-annual meetings, held each spring and fall. Questions about the PMWG may be directed to the PMWG Lead at 571-363-8630
Parts Management Training
The Defense Acquisition University offers a continuous learning module course, CLL 206, “Introduction to Parts Management.” The course is designed to be self-taught and should take about 1.5 hours to complete. Trainees may request access to the course at http://www.dau.mil.
