S2000M - What is it?

ASD Spec 2000M is an elaborate international military standard which integrates all material management requirements. Chapter 1 of the military version, ASD Spec 2000M (S2000M), is mandated by the UK Ministry of Defence (MoD) for use in high value equipment acquisition projects. The standard was originally developed as a civil standard, but is now widely used for major defence projects across Europe.

Projects using S2000M include Rafale, Tornado, Hercules C130J, Eurofighter, ASRAAM and Type 45.

SPEC 2000M is recognised alongside its sister standard ASD SPEC 1000D (for Electronic Documentation) and the USA's MIL-STD-1388 (for Logistics Support Analysis - LSA) as a source specification for the NATO CALS Acquisition Logistics Process Model.

The aim of SPEC 2000M's originators was to cut costs by internationally agreeing procedures, terminology, and an electronic means of exchanging information, in order to facilitate commercial traffic in spares and repair, throughout the life of an equipment program.

S2000M is maintained and updated by the S2000M Maintenance and Co-ordination Group (MCG) supported by the NATO Maintenance & Supply Agency (NAMSA). Using a common data set, S2000M defines business rules to be followed at various stages of the material management process, and provides various sets of standard messages that are to be used by business partners to exchange information in an unambiguous way.

The latest version (Issue 4.0) of SPEC 2000M is split into six chapters and provides a solution to the following business needs:



Provisioning - Spares Selection

Which spares do we require? How many of each?

Chapter 1A - defines how the supplier should provide information to the customer about the selection of support items and spares.

Parts Identification

How do we identify each component of a piece of equipment?

This chapter defines the structure and layout of an Illustrated Parts Catalogue, which could be used when equipment documentation is required on paper or microfiche, instead of being presented in digital format. Digital publications are defined in the sister standard : ASD SPEC 1000D - International Specification for Technical Publications Utilising a Common Source Database.



Item Identification

How do we identify products in a standard manner?

Chapter 1B - Codification provides you with the interfacing messages to define a standard reference for identifying spares between industry, the National Codification Bureau, and the customer


Procurement Planning

Price Negotiation

How much will it cost?

Once you, as a contractor or customer, have agreed what should be delivered based on indicative prices, you need to negotiate firm prices, based on quotation and response. The Procurement Planning chapter will accomplish this for you, and establish and update Customer Price Lists.


Order Administration

Managing the Orders

How is an order placed?

Chapter 3 - Order Administration, will show you how to place your order: accept it, reject it, amend it, query it, hasten it, cancel it, etc. You will also find shipment advice, acknowledgement of receipt, and mutual supply support arrangements between customers and contractors.




How do we guarantee rapid and accurate payment?

By integrating the payment functions, Chapter 4 - Invoicing provides the fastest and most efficient means to guarantee rapid and accurate payment for goods and services delivered. Just think of the time and money you could save by minimising bill-chasing, slashing errors, and not having money tied up in outstanding debts.


Repair Administration

Repair and Overhaul

How do we handle repairs?

Ensuring your spares perform effectively is dependent on accurate performance data, and on effective control of repair and overhaul procedures. This chapter covers repair and overhaul and provides the means to control assets which are temporarily out of action.


S2000M Light

Less complex projects

Do we have to use the full scope of the standard?

S2000M Light provides guidance on how to operate a simplified version covering the essential business processes, whilst adhering to the principles set out in the full specification.

The Benefits of S2000M

Key to the provision of cost effective material management is the ability to regularly, rapidly and efficiently exchange data between the contracting parties throughout the acquisition and support processes.

In today's highly technological market place, it is vital that computer applications utilise common standards so that vendor and client can exchange information rapidly and accurately at minimum cost; and that means with minimum human intervention.

S2000M enables users to exploit the maximum efficiencies offered by modern EDI techniques, using either the original SPEC 2000M protocol, or the UN/EDIFACT standard.

SPEC 2000M advantages can be enjoyed by any organisation, large or small, that uses the ONLY fully international EDI standard, EDIFACT. The EDIFACT standards are widely used around the world. They are supported on IT networks and Value Added Networks and a large number of subsets and software packages are readily available.

SPEC 2000M is controlled by the people who use it and have invested IT support to exploit it. So their interest is to protect your investment, whilst seizing the optimum benefits offered by a rapidly changing commercial world.
