ADMP-04 government activities for defence systems dependability

What it is

ADMP-04, Government Activities for Defence Systems Dependability, is a NATO Allied Dependability Management Publication promulgated in June 2025 as Edition A. It is unusual among the standards on this site in one important way: it is written for the government side of a defence programme, not the contractor. The document states its own scope directly - it "focuses on the government part of dependability activities" - and everything in it is framed as what a government dependability expert does, checks, or asks for, at each stage of a defence system's life.

That does not make it irrelevant to a supplier. It describes, in detail, what the customer's dependability staff will review, when they will review it, and what they expect to see. A contractor bidding into or delivering against a NATO or national defence programme is dealing with the other side of exactly this document.

A tailorable approach, not a fixed procedure

ADMP-04 sets out a "tailorable approach for identifying and managing the necessary dependability activities in each phase of the system life cycle." It covers two acquisition routes with different implications: a newly developed item, and an Off The Shelf (OTS) purchase, whether Commercial Off The Shelf (COTS) or Military Off The Shelf (MOTS). For OTS acquisition the document is candid that the government has little or no influence over the item's design, so the government's activity shifts from shaping requirements to assessing whatever usage, failure and warranty evidence a supplier can provide.

The life cycle it walks through

The bulk of the document is organised around the NATO Life Cycle Model from AAP-20: pre-concept, concept, development, production, utilisation and support, and retirement. For each phase it sets out the phase's general purpose, the dependability challenges specific to it, the government's own activities, and a set of "points of vigilance" the expert should watch for.

• Pre-concept and concept. The work is about setting realistic requirements before they are locked in. A government dependability expert supports market surveys, helps translate a user's operational expectations into a testable requirement, and helps prepare the specification document's dependability content. A government dependability plan should exist before development starts.
• Development. This is where design reviews happen. The government reviews the contractor's dependability plan against the Statement of Work, takes part in Preliminary and Critical Design Reviews, and implements a Failure Reporting, Analysis and Corrective Action System (FRACAS) or its earlier variant, DRACAS, to capture failure data as it emerges. The document is unusually direct about the limits of this review: the government "should not repeat all dependability activities conducted by contractor," because it lacks the resources and, more importantly, the responsibility to do so. What it produces instead is a formal government dependability report, an independent judgement on how much confidence the contractor's own dependability case deserves.
• Production. Government activity moves to monitoring conformance: reviewing acceptance test results, Engineering Change Proposals and any deviations for their effect on dependability, and keeping FRACAS running through manufacturing.
• Utilisation and support. The government dependability plan is updated to cover in-service monitoring of availability, reliability, maintainability, testability and safety, and to feed into decisions on modifications, obsolescence, and configuration changes.
• Retirement. The final activities cover demilitarisation and disposal planning, archiving the dependability data accumulated over the item's life, and capturing lessons learned for the next acquisition.

What a government dependability expert actually reviews

The document is concrete about the evidence trail, and this is where it is most useful to a supplier trying to anticipate what will be asked for. It expects a dependability plan, Failure Mode, Effects and Criticality Analysis (FMECA) worksheets built to a specific structure, reliability growth test plans with defined pass/fail criteria, and FRACAS or DRACAS records running from early in development. Three annexes make this concrete rather than abstract: a checklist for assessing a contractor's reliability activity, a checklist for assessing an FMECA, and a full worked example of an FMECA Data Item Description, complete with the severity categories (Catastrophic, Critical, Marginal, Minor) and probability levels a reviewer would expect to see used consistently.

Where it sits among the other NATO dependability publications

ADMP-04 is one of a small family. ADMP-01 covers how dependability requirements are established in the first place; ADMP-02 covers managing dependability once the item is in service; ADMP-03 covers classifying and analysing dependability events. ADMP-04 assumes those processes exist and builds the government's review activity around them. Its life cycle structure follows AAP-20, the NATO Programme Management Framework, and it draws on ALP-10 for how dependability interacts with Integrated Life Cycle Support, on STANAG 4370 and AECTP-100 for how environmental qualification relates to (but is distinct from) dependability qualification, on STANAG 4427 for configuration management, and on IEC 60812 for the FMEA/FMECA method itself. Nations are recommended, not obligated, to use it: the recommendation is recorded in STANREC 4174, which also recommends the underlying process standards a contractor is expected to follow. As with all NATO documents, ADMP-04 is free of charge and not sold; it is retrieved from the NATO Standardization Document Database or through a national standardization authority, never from a third-party copy.

What it does not cover

ADMP-04 explicitly does not tell a government how to organise itself internally to handle dependability - it leaves that to each nation. It is not a certification scheme: nowhere does it describe an accredited body, a notified body, or any award of "ADMP-04 certification." What it describes instead is the government's own internal surveillance of the contractor's evidence, formalised in design reviews and a government dependability report. It also does not set the applicable tier for a given programme - that is a matter for the contract and the customer's quality clause, not for this document or for any vendor reading it on your behalf.
