Diminishing Manufacturing Sources and Material Shortages (DMSMS)


A Diminishing Manufacturing Sources and Material Shortages (DMSMS) issue is the loss, or impending loss, of manufacturers or suppliers of items, raw materials, or software. The Department of Defense (DoD) loses a manufacturer or supplier when that manufacturer or supplier discontinues production and/or support of needed items, raw materials, or software or when the supply of raw material is no longer available. While traditionally thought of as applying to electronic items, it is important to be cognizant that a DMSMS issue can arise regarding any item within a system, including software and non-electronic components—materials and structural, mechanical, and electrical (MaSME) items.

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 2016, 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.
