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.
