About DMSMS
A DMSMS issue is the loss, or impending loss, of manufacturers or suppliers of items or, raw materials. The DoW 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 DoW-wide strategic DMSMS objectives.
• Prepare and publish guidance documents.
• Facilitate common, collaborative resolutions to cross-cutting DMSMS issues.
Guidebook
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 2026, highlights the most effective, proactive practices being used across DoW 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.
