This instruction establishes the Integrated Life Cycle Management (ILCM) guidelines and procedures for Air Force (AF) personnel who develop, review, approve, or manage systems, subsystems, end-items, services, and activities (for the purpose of this publication referred to as programs throughout this document) procured under Department of Defense (DoD) Instruction (DoDI) 5000.02, Operation of the Defense Acquisition System.

The Weapons Systems Impact Tool (WSIT) enables Government program managers to research the relationships between parts, weapon systems and specifications and standards.

The Department of Defense (DoD) Adaptive Acquisition Framework (AAF) establishes a set of acquisition pathways that are designed to allow for tailored strategies that support the delivery of better solutions and capabilities faster. The AAF approach emphasizes transparency, speed of delivery, continuous adaptation, and frequent modular upgrades.

This change in how the DoD approaches system development requires program managers, system engineers, product support managers, and contractors to design tailorable parts management approaches, including engineering design considerations, that align with the specific acquisition pathway selected. Engineering design considerations include traditional design, system security engineering, and supply chain risk management.

This publication is intended to be used by government acquisition activities and defense contractors. The document provides government and industry managers guidance to support achieving a more disciplined and integrated parts management approach. The parts management approach ensures that acquisition activities and defense contractors meet system requirements and balance the costs and risk of selection considerations for DoD programs.

This version of the SD-19 document updates the December 2013 version, and it introduces a new parts management paradigm and vision that are achieved by increasing the level of discipline applied in program office part selection oversight by emphasizing and applying best practices found in MILSTD-11991—General Standard for Parts, Materials, and Processes—and the SD-26—DMSMS and Parts Management Contracting Guide. The new paradigm also relies on collecting and analyzing records on parts selection oversight activities and their effects on cost, schedule, and performance; and, obtaining part selection data and using tools to analyze the data in support of best practices.

This manual assigns responsibilities and prescribes the procedures for implementing the DSP.

This white paper provides cost implications of introducing parts into systems and how costs can be reduced through parts management

Establishes policy, assigns responsibilities and functions, and prescribes relationships and authorities for the DASD(SE) pursuant to section 139b of title 10, United States Code (Reference (a)) and in accordance with the authority in DoD Directive 5134.01 (Reference (b)) and DoD Instruction 5000.02 (Reference (c)).

This standard establishes the requirements for parts, materials, and processes (PM&P) for use during the development, production, and sustainment of military systems. These requirements directly apply to the design, manufacture, and support of military systems. This standard also provides criteria to evaluate the suitability of commercial off-the-shelf (COTS) items for incorporation into military systems.

The Defense Standardization Program Office (DSPO) changed the status of SD-18 from active to legacy. This means the SD-18 will not be updated, but remains accessible on a website located at:

 https://www.navsea.navy.mil/Home/WarfareCenters/NSWCCrane/Resources/SD18.aspx 

Please be cognizant of this status change when using SD-18. The SD-18 is a guide that offers extensive information for the selection, design, procurement, and assessment of parts used in military systems. It was last updated in 2018. Preparing Activity: OSD-SO

SD-18 "Parts Requirements and Application Guide" provides guidance when using military and commercial parts in military environments. It provides part acquisition guidelines for Program Managers, System Program Offices, and Original Equipment Manufacturers. SD-18 provides guidance on how the Department of Defense and its contractors can cooperatively select devices that will result in the lowest cost of ownership for the DoD.
