FOREWORD

1. This standard is approved for use by all Departments and Agencies of the Department of Defense.

2. This standard covers the essential requirements in order to meet the mandatory standardization parts

management requirements of the Defense Standardization Program (DSP) Procedures, DoDM 4120.24. Parts 

management is a design strategy that seeks to reduce the number of unique, specialized, and defined problem parts

used in a system (or across systems) in order to enhance standardization, reliability, maintainability, and

supportability. It also mitigates parts obsolescence occurrences due to diminishing manufacturing sources and

material shortages (DMSMS). These inherent benefits result in increased operational and logistics readiness,

enhanced interoperability, reduced logistics footprint and total ownership cost. Effective parts management helps

program managers achieve their objectives.

3. This standard is in support of acquisition strategies and systems engineering practices of DoDI 5000.2, 

“Operation of the Defense Acquisition System.” When used in conjunction with SD-19, “Parts Management Guide,” it 

provides definition of parts management needs in contracts, setting up a parts management process for prime 

contractors, suppliers and subcontractors, and identifies an efficient means of a manageable part selection process 

for persons, companies, and Government activities. This document is not intended for satellite and launch vehicle 

parts, materials, and processes applications but may be applied to space system ground and user segment 

applications.

4. DoD is currently developing a parts management tool for the users to access parts management information 

through a single point of entry. The intent of the tool is to provide engineering and material data relevant to design, 

parts availability, parts obsolescence, and parts program management information. This tool should aid the 

acquisition offices, designers, and specification preparing activities in making informed decisions on parts 

management programs, parts selection, and standardization. For the current status of these tools see 

http://www.dsp.dla.mil/.

5. Comments, suggestions, or questions on this document should be addressed to Defense Logistics Agency Land 

and Maritime, ATTN: VAT, P.O. Box 3990, Columbus, OH 43218-3990 or emailed to

1. SCOPE

1.1 Scope. This standard provides requirements for the implementation of an effective Parts Management 

Program (PMP) on Department of Defense (DoD) acquisitions. This document supports acquisition strategies and 

systems engineering practices. This document also provides performance-based parts management processes and

practices which are intended to be adapted to individual program needs and which provide appropriate latitude for 

innovative approaches and design solutions by the contractors.

1.2 Objective. The objectives of a PMP are to reduce logistics footprint and total life-cycle cost, and also increase 

logistics readiness by:

a. Promoting interoperability.

b. Enhancing the interchangeability, reliability, and availability of parts.

c. Minimizing diminishing source impacts and parts obsolescence.

d. Assisting in meeting end item performance.

e. Assisting with parts selection and qualification procedures.

f. Minimizing the proliferation of parts and drawings through standardization.

1.3 Applicability. This document provides requirements for the application of a PMP to acquisition contracts for 

new design, modifications of DoD weapon systems, and equipment acquisition programs. Applicability of individual 

aspects of the requirements contained herein is dependent upon program business and support strategies, 

technologies used, expected service life, etc. The components of the Off-The-Shelf (OTS) and Non-Developmental

PARTS MANAGEMENT PLAN DEVELOPMENT GUIDE

B.1 GENERAL

B.1.1 Scope. This Appendix is not a mandatory part of the standard. The information contained herein is intended 

for guidance only. This appendix is intended to provide general guidance and considerations in the development and

implementation of a parts management program within a company. The program developed is intended to be 

applicable to the design development, engineering development, production, modification, test, and maintenance of a 

program. The appendix is provided to help guide the baseline process for parts management. However, a specified 

format is not provided as companies are allowed to use their own formats.

B.1.2 Purpose. This document provides guidelines for the preparation and implementation of a parts management 

plan. This parts management plan is expected to:

a. Improve the potential for part commonality/standardization.

b. Provide an integrated process for obsolescence management.

c. Take advantage of emerging technologies.

d. Improve risk mitigation and management.

e. Increase the speed of transitioning from development to production.

f. Improve forecasting of parts to leverage sourcing needs.

B.2 Applicable documents. Deleted.

B.3 Definitions. Deleted.

B.4 Parts Management Plans.

B.4.1 Implementation. This guideline is intended to be used to coordinate at the program level the selection, 

application, management, and procurement of parts throughout the design, development, fabrication, test, and 

maintenance phases of a program.

B.4.2 Application. Programs will request contractual approval in accordance with the CDRL for their parts 

management plan. This plan should control the selection of all parts introduced into the design and any changes to 

the approved configuration baseline of the equipment.

The program will be consistent with the intent to optimize system spares, standardization, provisioning, logistics 

support, interoperability, reliability, and maintainability.

Program controls should further provide a process for the elimination of weaknesses or defects uncovered during all 

levels of testing; whether it is a part, module, or equipment. The program should be integrated with appropriate part 

reliability, procurement, and quality assurance activities.

B.4.3 Selection. Fulfillment of design objectives is the prime consideration in the selection of parts. The plan

should address the criteria used to ensure suitability of a part’s intended use to the required application. Selecting 

parts using sound evaluation principles reduces risk and improves the chances that equipment will perform reliably.

A simplified list of the ground rules and activities needed for assuring the selection and control of parts is listed below. 

Utilization of these steps is recommended as a method of selection, maintenance, and control of parts:

a. Determine part type needed to perform required function and environment it is expected to operate in.

2. Long procurement lead time.

3. High cost item.

4. Perform cost/technical trade-offs.

5. Expected life cycle.

6. Part requires qualification.

c. Determine Part Availability.

1. Part on existing parts list.

2. Normal delivery cycle.

3. Part subject to obsolescence.

4. GIDEP; Alert, Problem Advisory or Product Change Notice Implications.

5. Standard Mil-Part, with Qualified Products List (QPL) Source(s).

6. Source Control Drawing exists for part.

7. Multiple sources of supply available.

d. Reliability level for a part appropriate for its intended application environment.

e. Screening methods to determine if a part is available in the required temperature range.

Appendix B

B.4.4 Program parts list or BOM. For parts management, the prime contractor will prepare and maintain a parts 

list or BOM which contains, as a minimum:

a. Part type.

b. Part description.

c. Manufacturer’s part number.

d. The part manufacturer(s).

e. General information indicating part qualification status.

f. The part specification number (generic and detailed).

g. Quantity used per assembly.

A program BOM is maintained for all products developed for the program. The BOM consists of all parts used in the 

equipment. All parts selected in accordance with the criteria established within this plan are considered approved for 

use on the program. The BOM is available for review by the Program Manager upon request.

B.4.5 Managing sources. Source management is a key factor in the standardization of parts. The trend towards 

OTS items is putting increased emphasis on source management to ensure quality. This must be achieved through 

the development of preferred suppliers that provide the greatest competitive advantage using a variety of methods:

a. Physical (manufacturer’s) facility and industry surveys.

b. Supplier quality history.

c. GIDEP history, participation and/or no response.

d. Technical capability of similar products.

e. Qualification of new parts or similar devices.

f. Shared data through use of site databases and internal alerts.

g. Shared experiences gathered through the use of Lessons Learned databases, sites, and corporate commodity 

teaming and standards or parts management organizations.

h. Part performance feedback through failure analysis reviews and product improvement.

i. Subcontractor/supplier management and controls.

Major subcontractors should:

a. Maintain their own internal systems and establish and conduct parts management activities.

b. Create, coordinate, and submit Parts Management Plans to the prime contractor for approval.

c. Flow down parts management requirements to subcontractors as appropriate.

Parts manufacturers should:

a. Promote communication with the prime contractor and their suppliers to ensure feedback for part failures, 

manufacturing changes, and customer needs.

b. Manage internal materials and processes to provide control and a consistent product.

All of these methods may be used in varying degrees as part of supply chain management.

B.4.5.1 GIDEP. The component engineering or equivalent organization will participate in the GIDEP Program.

B.4.6 Part evaluation and qualification.

B.4.6.1 Part qualification test. All parts will be qualified for their intended application by test, analysis, or similarity.

Appendix B

B.4.6.2 Part and supplier quality. Provisions for assessing part suppliers and part quality such as statistical 

process control data, audits, past performance, etc. will be addressed.

B.4.7 Parts selection and standardization. The plan should address a part selection order of preference to 

maximize standardization and reduce life cycle costs. Preferred parts have a history of proven reliability withstanding 

rigorous testing and performing at stated levels. Their use decreases the number of maintenance actions and 

potentially precludes failures that could cause mission failures or loss of life.

Parts are designated as preferred based on the following:

a. Product design requirements (specifications/standards).

b. Part selection criteria.

c. Current parts lists.

d. Standardization.

e. Life cycle cost.

f. Reliability.

g. Supportability.

h. Interoperability.

i. Maintainability.

j. Emerging technologies.

k. Design reuse.

l. Lessons learned.

m. GIDEP alerts.

n. Diminishing Manufacturing Sources and Materiel Suppliers (DMSMS).

o. Part currently in inventory.

p. Preferred suppliers.

Above listing is in no particular order. No ranking is intended by order.

B.5. Parts management critical issues.

B.5.1 Substitute and alternative parts. The process for the management, definition, and documentation of 

substitute and alternative parts will be addressed. In specifying the part replacement process, the contractor will 

ensure that the substitute/alternative part meets the requirements of this parts management plan.

B.5.2 Counterfeit parts. The parts management plan shall address the detection, mitigation, and disposition of 

counterfeit parts. Electronic, electrical, and mechanical parts are to be addressed. AS5553 should be used as 

guidance for electronic parts.

B.5.3 Lead-free electronic parts. The process for managing Lead-free electronic parts should include an 

assessment of the critical risks and actions taken to control those risks. The contractor will ensure that the parts used 

to control risk meets the requirements of this parts management plan. SAE GEIA-STD-0005-1 may be used for 

guidance for lead-free electronic parts.
