What is the best way to track maintenance related data (i.e. MTBF, MTBCF, MTTR, etc.) for a COTS product? Is there a class for this?
Background: I work on a space environmental monitoring system that is 100% COTS. The system is fielded and maintained by a contractor and they do not currently track failure rates of the system. There are other users of this COTS product but it is a very specialized piece of equipment and there is no maintenance data available on the internet or from the manufacturer for things like MTBF, MTBCF, MTTR, etc... I would like to start tracking this data but I'm not sure how to go about it.
In order to collect, analyze, track, and report reliability and maintainability failure information (e.g., MTBF, MTBCF, MTTR), recommend you modify the contract (see ref 12) to require the contractor to provide this information for the COTS-based space environmental monitoring system. Here are some recommended steps to consider:
Develop a performance work statement (PWS, ref 15) that requires the contractor to use a Failure Reporting and Corrective Action System (FRACAS, see ref 2) to collect, analyze, and track reliability and maintainability failure information (e.g., MTBF, MTBCF, MTTR). Be specific on what data is required and how it will be measured/calculated (see refs 9 and 13).
The PWS must include a Contract Data Requirements List which requires the contractor to deliver this information in a specific format and when (CDRL, see item 17) along with a Data Item Description (DID, see refs 4 and 17) which addresses the content and data to be included in the deliverable. The Life Cycle Logistician should work closely with the Contracting Officer and Engineer on this.
Alternative: As an alternative to incorporating a specific deliverable into the contract/PWS for delivery of FRACAS reports, you can require the contractor to establish/maintain a Logistics Product Database (e.g., ref 18) which allows the exchange of logistics product data between the contractors' LPD database (i.e., ref 8) and the government's LPD database (i.e., ref 7).
MIL-HDBK-217F Reliability Prediction of Electronic Equipment (i.e., ref 1) is used to estimate initial baseline reliability predictions for electronic equipment (i.e., COTS). These predictions would later be replaced by actual FRACAS data.
References 10, 16 and 19 provide background information on how to set up a Diminishing Manufacturing Sources and Materiel Shortages (DMSMS) program to manage obsolescence issues which is a major problem with COTS-based systems.
Reference 11 provides information on how to set up a Reliability Growth program to improve system reliability.
