SD-19 Parts Management GuideIn todays acquisition environment-characterized by rapidly changing designs, increased risk for Department of Defense DoD weapon systems and equipment acquisition contracts due to an increase in the use of commercial part types, offshore manufacture of parts, and Diminishing Manufacturing Sources and Material Shortages DMSMS-the need for contractors to have an effective Parts Management Program PMP is greater than ever before.The PMP is an integral part of the acquisition process for design, development, modification, and support of weapon systems and equipment.

A contract normally begins with a solicitation requesting the submission of offers or quota- tions to the government. The solicitation and its supporting documents establish the technical and management requirements that must be addressed in the contractor's proposal. The con- tract will normally consist of several individual specifications, including the SOW, the Prime Item Development Specification, and the Contract Data Requirements List (CDRL).

The most effective PMPs are implemented during the initial contract and contract review process. Therefore, it is imperative that the engineer or individual responsible for parts man- agement be involved up front so that all areas affecting parts management can be addressed.

The Contract Statement of Work

Parts management requirements, if needed, should be implemented in the contract through wording contained in the contract SOW, statement of objectives (SOO), or performance work statement (also referred to here as an SOW). The SOW can be written in two different ways. First, the government can write the SOW and ask the contractor to respond with a proposal. Alternatively, the government can include an SOO in the solicitation and ask the contractor to write and submit an SOW within a proposal in response to the SOO.

The SOO is usually a brief statement of the government's objectives for a program. It is not likely to contain enough detail to address parts management. If the solicitation contains an SOO, the contractor's SOW will need to address parts management.
