Selecting a non-traditional part, such as selecting an automotive grade connector for use in an aerospace system, can be tricky business. Many alternate grade parts have shown better quality than the COTS (Commercial Off the Shelf) parts and could be used as alternate to Military grade parts for certain applications as long as the mission and application for these products can tolerate reduced short term or long tong term quality and reliability considerations.
For example; although automotive grade electronic parts are not subjected to the rigors of qualification and testing that parts designed for aerospace applications undergo, their performance in an aerospace environment tends to be better than COTS due to the line statistical process control and other review processes used their manufacture. The issue is, most users don't consider the application driven risk tolerance that automotive grade products may have because they undergo less rigorous screening (quality, conformance, inspection, and testing) than that of a Military grade product.
Additional measures can be employed to reduce the risk of using non-traditional parts, ensuring reliability and performance in the intended application. One solution to using non-traditional parts may be conducting additional part qualification and screening and part derating to ensure the part can meet the specific intended application. Additionally, existing standards, AEC Q specifications for automotive electronics for example, may help to predict performance and reliability. Effective measures can also be in form of process changes, such as planning for more frequent part refresh, building in redundancy, and providing additional insulation against environmental extremes.
Whatever the approach, implementing additional measures will likely add to overall part acquisition cost and time, which must be weighed against the benefits of using a non-traditional part. However, the benefits can be considerable.
Beyond the potential cost savings, a non-traditional part may offer improved technology or a value-added reduction in size and weight. In addition, a non-traditional part may be more readily available from a larger supplier base than an aerospace grade part, offering future reductions in lead times and costs.
In the end, selecting a non-traditional part may be just the right choice.

Dear Team –
The holiday season brings thoughts of joy and gratitude, and there's no better time to express my thanks and sincere appreciation for your amazing hard work and dedication. Reflecting on the year, it's clear to see how hard you've worked. Your drive and determination helped us to get where we are today and I couldn't have done it without you.
2019 was a very fruitful year for achievements by the DMSMS and Parts Management communities that ended on a high note with a very successful DMSMS Symposium on Strengthening Parts and DMSMS Management to Improve Readiness and Affordability. We also combined the Parts Management and DMSMS Working Groups and successfully conducted our first joint meeting in September with participants from both Government and Industry. This offers significant advantages in that parts selection and management during design is now fully integrated with DMSMS and obsolescence management.
Our accomplishments fall into three major categories—funding DMSMS resolutions, improving DMSMS management effectiveness and efficiency, and issuing new policy and guidance. Contributions in each of these areas have a direct impact on the warfighter in that they improve operational availability and reduce cost.
In the area of securing funding for DMSMS resolutions, descriptions were published of the ways in which the Army, Air Force, and Defense working capital funds (WCFs) can be used to finance DMSMS resolutions. In addition, the legal basis for using WCFs in this manner was documented. Finally, clarifications were recommended for ambiguities in DoD's Financial Management Regulation on funding the non-recurring engineering and testing on resolutions for systems in sustainment.
In terms of increased efficiency and effectiveness, a major report on DMSMS record keeping and metrics was published. That effort gave detailed examples of how the entire chain of command could use data to improve DMSMS management. A second, very impactful event was the dissemination of a new contracting standardization document (SD-26) that provides sample contract language, guidance on when to use that language, and associated data item deliverables and contract data requirements lists. In addition, new training was developed on the DMSMS management plan, software obsolescence, and component research. Furthermore, a standardized DMSMS and parts management training/certification program was initiated. Efforts involving the Government Industry Data Exchange Program (GIDEP) to enable cooperation in resolving issues among different DoD organizations have also begun. Finally, instructions were issued on how to construct bills of material if they were not included as contract requirements.
In the policy arena, a new DOD Instruction and Manual on DMSMS management have been drafted; the coordination process is imminent. DMSMS guidance in the SD-22 is also being rewritten.
This information can be found on our DAU websites: DMSMS Knowledge Sharing Portal (DKSP) (https://www.dau.edu/cop/dmsms/) or our new Parts Management Knowledge Sharing Portal (PMKSP) (https://www.dau.edu/cop/pmksp/).
All of the above contributions have been the result of outstanding team effort. Thank you so much for everything you do to make us so successful.
Wishing you warm greetings for a happy and healthy holiday season.
Best wishes to you and your family for a prosperous New Year!
In case you hadn't seen it already, the October-December 2017 issue of the Defense Standardization Program Journal is dedicated to the topic of Diminishing Manufacturing Sources and Material Shortages (DMSMS). No system or program is immune from DMSMS issues; they are inevitable. They are not confined to piece parts or devices; and can occur at the part, module, component, equipment, or system level and affect short- and long-lived systems; repairables and consumables. DMSMS issues are also not limited to defense-unique items; commercial off-the-shelf (COTS) items represent a significant obsolescence problem, because such items are most susceptible to market forces.
This issue of the DSP Journal addresses the enduring challenge of DMSMS and obsolescence, and describes ongoing efforts, DMSMS mitigation approaches, and lessons learned.

The U.S. Army Aviation and Missile Research, Development and Engineering Center's (AMRDEC) Obsolescence Engineering team has created a system called the Multifunctional Obsolescence Resolution Environment tool-database (MORE). MORE is a government-owned engineering analytical obsolescence and DMSMS management information system, maintained by AMRDEC.
Proactively identifying DMSMS issues as soon as information becomes available increases the number of resolution options available and creates opportunities for an increased number of lower-cost alternatives. This allows for more time to address the problem before an impact occurs. If a program does not discover a DMSMS issue until there is a failed attempt to buy an item, resolution options often are limited, usually only more expensive alternatives are feasible and may impact readiness.

As you know, our purpose is to facilitate the implementation of DMSMS management throughout the DoD in order to proactively reduce, where possible, adverse impacts on readiness, schedule, and cost due to DMSMS issues. We serve as the focal point for developing and revising DoD DMSMS policy, guidance, and management strategies. We are the Champions for proactive DMSMS management best practices, synergies, and standardization. It makes me happy to see more and more cooperation, communication, efficiency, and synergy amongst all of us. Collaborations like these are key to our success. It is with great pleasure that I work with you all every day and am able to witness the outstanding support that you provide Program Offices as they tackle DMSMS issues.
I am looking forward to showcasing more success stories like this (via Journals and the Conference) so please if you have something to share please let me know.
Your expertise and skills are needed!
You are invited to submit an abstract for your proposed presentation for the following tracks:
Abstract Submission Deadline is July 31, 2017.
You are invited to attend 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 DD2354 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.
