Welcome to the DMSMS Knowledge Sharing Community Homepage !
The Diminishing Manufacturing Sources and Material Shortages (DMSMS) Knowledge Sharing Portal (DKSP) is focused on being a non-biased one-stop provider of DMSMS related information, resources and material to empower the Department of Defense (DoD) community, both Organic and Industrial, to implement best practices for monitoring, tracking, resolving, and performing analytical logistic and engineering analysis related to obsolescence impacts. Utilization of the DKSP as a resource facilitates optimal resolution, test, parts management, design, upgrade and redesign methodologies, thereby minimizing detrimental weapons systems readiness resulting from DMSMS and obsolescence impacts.

​Good day all, 

I am currently building a DMS/MS program. We are developing Lexicon to use throughout the Coast Guard to hopefully build a standard framework. What I am requesting the community possibly help me with is vetting what I have developed. During my DAU training, I have found these terms but as I developed these terms, I have not been able to find the reference.

The terms are below:

 OEM End of Production -  A part of a larger system that is no longer manufactured by the original manufacturer. ​

End of life (EOL) or End of sale (EOS) / End of Production​
Original manufacturers typically begin issuing updates regarding EOL in year 5. The original manufacturer will no longer be producing or selling this product, but third-party maintenance is available for most products.

OEM End Of Support Date –  ​OEM has identified as the date they will no longer support the Product​ 
When the OEM will no longer provide repair services, repair parts, firmware or software updates, cybersecurity patches, etc.​
End of service life or End of support EOSL / End OEM of Support Date​: At this point, the original manufacturer will start to issue EOSL updates. It may also stop issuing support. Now, the product is no longer sold by the manufacturer at all, there will be no more OS updates, and they do not renew support agreements.

Govt Defined Obsolete Part/System – ​
Most often occurs sometime after the OEM EOS Date, when the Government is unable to (afford to) ​
ensure the Product meets Operational Availability (AO), Reliability, or Maintainability requirements;​
A determination that the Product can no longer meet Operational, Functional and Non-functional Requirements: Interoperability, Compatibility (Interface), Security, Performance (bandwidth), etc.; ​
When the Government can no longer to afford to support the Product to meet AO or other Operational Requirements (e.g., RFDS PCBs increased 10x (from $4K to $46K), rendering it unaffordable to sustain).​​

When the LTB (Life Time Buy) the process for purchasing discontinued Components or Products (i.e., those no longer available from Flextronics, a Component Supplier or any other distribution channel) to span Product Life or Support Life requirements, as applicable, for that Component or Product

Thank you all.

Very Respectfully,

If I place an OEM on contract and their subcontractor goes out of business or has an obsolete part, shouldn't the OEM be responsible for funding the fix or does it rely on the Government?​

​Please join us for a COTS Selection Checklist Webinar on June 22, 2021 at 1500 EST. This webinar will include an explanation and demonstration of the proposed COTS checklist and provide attendees the opportunity to learn and ask questions about this valuable resource supporting parts evaluation and management.

Even though Commercial Off-The-Shelf (COTS) assemblies are becoming more common in defense systems, there are no standard procedures used by the parts management community (both Industry and Government) to select COTS assemblies.  To address this problem, the DoD Parts Management Working Group formed a Strategic Objective team to examine the problems associated with choosing and using electronic COTS assemblies and to evaluate implementing common procedures for selecting electronic COTS assemblies throughout the entire program lifecycle.  Over a two-year period, this Team has successfully researched and developed a checklist for selecting electronic COTS assemblies for use in safety critical or mission critical Aerospace, Defense, High Performance, and Space applications.  This checklist has undergone peer review and is scheduled to be rolled out in late 2021. 


Register in advance for this webinar:

After registering, you will receive a confirmation email containing information about joining the webinar.

Team--Need some guidance. We are in the LRIP phase, and have been notified of DMS issues requiring end-of-life buys. The problem is, we need to buy enough to also support the quantities that will be installed in full rate production (through 2031), but do not yet have a FRP decision (~2024). Has anyone had to request authority to buy that far ahead of need? This buy would avoid very costly redesigns, so it seems like the obvious choice, but I can't find anything on HOW to get this ball rolling to get approval. Thanks in advance!

Edit: this is my first time using this forum and i keep getting errors when setting up my profile... so I can be reached at if anyone has recommendations! Thanks!
