Diminishing Manufacturing Sources and Material Shortages (DMSMS)


A DMSMS issue is the loss, or impending loss, of manufacturers or suppliers of items or, raw materials. The DOD loses a manufacturer or supplier when that manufacturer or supplier discontinues production or support of needed items, raw materials, or software or when the supply of raw material is no longer available. The DMSMS program was established to facilitate the implementation of proactive DMSMS management throughout DoD to reduce the adverse effects of DMSMS issues on readiness, schedule, and cost. To accomplish this, we do the following:

• Create and revise DoD DMSMS policy, guidance, and management strategies.
• Champion proactive DMSMS management best practices, synergies, and standardization through education, training, and outreach in DoD and industry.
• Define and assess DMSMS management effectiveness across DoD.
• Establish and pursue DoD-wide strategic DMSMS objectives.
• Prepare and publish guidance documents.
• Facilitate common, collaborative resolutions to cross-cutting DMSMS issues.

Knowledge Portal

The DMSMS Knowledge Sharing Portal (DKSP) is supported by the Defense Standardization Program Office (DSPO) to be a non-biased source of products, services, information, educational resources, data interchange techniques, interactive forums, and related material to empower the DoD community (organic and industrial) to implement best practices for monitoring, tracking, resolving, and performing logistic and engineering analyses related to the impact of obsolescence. DKSP resources are extensive and include: a comprehensive listing of DMSMS tools (free and subscription based); DMSMS training materials; a library containing directives, manuals, presentations, papers, and newsletters; a calendar of DMSMS related events; and links to other useful sites and points of contact.


DSPO publishes SD-22, DMSMS: A Guidebook of Best Practices and Tools for Implementing a DMSMS Management Program. This guidebook, which was updated in January 2021, highlights the most effective, proactive practices being used across DoD to help program managers reduce the risk of obsolescence. The guidebook presents basic methodology to assist program managers with establishing DMSMS programs and analyzing the results in regard to the basic parameters of cost, schedule, and performance. The SD-22 also identifies assorted measurement tools that may be useful in analyzing and tracking the effectiveness of DMSMS programs. The guidebook addresses both electrical and mechanical parts obsolescence issues. Program managers should make the DMSMS guidebook the desktop reference for quickly pinpointing key actions required in managing DMSMS issues and concerns.


The Defense Acquisition University (DAU) offers a number of continuous learning modules that deal with DMSMS and obsolescence. A listing of the available courses is provided in the left-hand menu.

Parts and Material Management Proven Processes - This monthly series provides a cross-functional forum for promoting, shaping, and coordinating government and industry approaches to effective DMSMS and parts management. The series leverages subject matter experts to increase your knowledge, awareness and ability to support your program effectively.

Parts and Material Management Conference

The annual DMSMS conference is now the Parts and Materials Management Conference (PMMC). The PMMC provides the opportunity for attendees from DoD, other government agencies, industry, and academia to interact and exchange ideas and learn about new tools and technologies that can impact parts and materials management. For more information on the upcoming conference, please visit the official PMMC Conference site.
