Defense Standardization Program

The DLA Consumable Hardware team participates as a Standardization Management Activity (SMA) in the Defense Standardization Program for consumable hardware commodities and the THDS Standardization Area. We standardize to provide the warfighter with equipment that is interoperable, reliable, and technologically superior at the lowest cost. Items bought to specifications usually require less lead-time, reduced stock levels, and result in fewer back orders. 

Lead Standardization Activity

DLA Consumable Hardware has the Lead Standardization Activity (LSA) responsibility for DLA consumable hardware commodities, and the THDS Standardization Area.

This support involves the approval of standardization project numbers in the generation/modification of standardization documents, coordination review of standardization documents and coordination of standardization documents such as Military/Federal specifications and standards, Non-Government Standards (NGSs), and Commercial Item Descriptions (CIDs). We also look for opportunities to standardize items that are procured by the DLA Consumable Hardware team in order to lower cost and reduce cycle time.

Qualified Products List (QPL)

A Qualified Products List (QPL) is a listing of products or family of products that have met the qualification requirements set forth in the applicable specification, including appropriate product identification, tests or qualification reference, and the name and plant address of the manufacturer and authorized distributor. A QPL listing is used by government activities to determine approved sources of supply for items they wish to procure.

The need for QPL is determined by verification requirements in a specification. These requirements can only be justified if:

• it is determined that time to conduct the tests identified in the applicable specification would exceed 30 days
• or special equipment not commonly available is required to conduct the tests
• or the tests are required for emergency life-saving equipment

Further specifics regarding the Defense Standardization Qualified Products Program can be found at the Defense Standardization Program Website .

Provisions Covering Qualified Products Lists are found in the SD-6 .

An applicant who wants more information or clarification on having their product qualified should:

• Register for an account at ASSIST
• Contact the Preparing Activity indicated in ASSIST for the specification they wish to have their product qualified to.

Value Management (VM) Program

Value Management (VM) is an overarching program that was established by Office of Federal Procurement Policy for the purpose of reducing costs, increasing productivity and quality and improving reliability and maintainability.

VM is an effort that analyzes functions of systems subsystems, equipment, services and supplies for achieving the essential functions at the lowest life cycle cost consistent with required performance, reliability, quality and safety.

DLA's Consumable Hardware team maintains VM Programs. Several functional areas of the VM Program provide services that are oriented toward reducing the costs of items yet maintaining the necessary safety, quality, reliability, and maintainability aspects of items.

Some of the Value Management programs supported within DLA Consumable Hardware are:

• Value Engineering (VE)
• Price Challenge
• Reverse Engineering
• Sustaining Engineering
• Should Cost
• Spares parts Breakout
• Change Proposal (VECP)
• Replenishment Parts Purchase or Borrow (RPPOB) Program

Industry and government employees may submit VE/VM requests for assistance through the Value Engineering Assistance Request Module .

NOTE: To access the ARM tool, first time users without a DoD Common Access Card (CAC) must register for access (PDF) through DLA’s Account Management and Provisioning System (AMPS).

Qualified Suppliers List for Manufacturers (QSLM) | Qualified Suppliers List for Distributors (QSLD)

This qualification program encompasses the best industry practices and incorporates these elements into the DLA Troop Support Construction & Equipment & Industrial Hardware supply chains' acquisition process. Through the program, we pre-qualify manufacturers and/or distributors to supply certain items based on an assessment of the provider's applied process controls. Applicants must demonstrate that the controls which they have in-place and in-use on a daily basis comply with the established QSL criteria, providing maximum assurance that the products procured conform to specification and contractual requirements. The table below links to the criteria, provisions, and application forms for the six QSL commodities. (Note that the same forms are used for initial qualification, 3-year renewal, revision and re-qualification following removal or disapproval.)

Visit the QSLM/QSLD page for full descriptions and lists of criteria & provisions, qualified companies and a list of removed companies.

Organic Manufacturing Program

Organic Manufacturing (OM) is part of DLA Consumable Hardware's Value Engineering offerings, and utilizes the OM process as a supplemental tool to the spares procurement process. The decision to use an in-house or organic’ source of supply may be based on high costs for low quantity purchases, long production lead-times by private industry, diminishing manufacturing sources and material shortages (DMSMS), or a lack of bids from private industry.

OM assists the Procuring Agency in establishing relationships with defense manufacturers, assesses expertise, confirms quality assurance and technical protocols for public manufacturing organizations and oversees project order implementation.

Some functions of the OM Offices for DLA Consumable Hardware include:

• Coordinate with organic manufacturing sites;
• Authenticate and validate part information;
• Follow-up on request for quotes and project orders;
• Serve as the central POC for all communications to track projects;
• Maintain a listing of OM sites, POCs and their capabilities;
• Maintain database of DLA Consumable Hardware NSNs manufactured organically;
• Promote the process within DLA Consumable Hardware and organic sites; and,
• Work with DLA HQ to develop and update OM policy for DLA Consumable Hardware and the DoD.
