Diminishing Manufacturing Sources and Material Shortages (DMSMS)


DMSMS is defined by the DoD as the "...loss or impending loss of the last known manufacturer or supplier of raw material, production parts, or repair parts," and by industry as the "...loss or impending loss of the original manufacturer or supplier of raw material, production parts or repair parts." An obsolete device is part of a larger system that is no longer manufactured by the original manufacturer. DMSMS management is a multidisciplinary process to identify issues resulting from obsolescence, loss of manufacturing sources, or material shortages; to access the potential for negative impacts to readiness; to analyze potential mitigation strategies; and then to implement the most cost-effective strategy.

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.

DMSMS Conference Information

The Diminishing Manufacturing Sources and Material Shortages (DMSMS) 2017 Conference scheduled for December 4-7, 2017 in Tampa, Florida. Qualified attendees (active US Military, Government or current DD254 on file) will also be able to attend the concurrent Defense Manufacturing Conference at no additional expense, giving you access to more technical information for the same travel cost. The expanded Exhibit Hall will include all the leading organizations from both the DMC and DMSMS communities. Agenda, registration, and lodging information will be posted on this website. You can also view links from past conferences, access proceedings and see information about prior individuals and teams honored for their management of DMSMS programs.
