OBSOLESCENCE MANAGEMENT –
APPLICATION GUIDE
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62402 has been prepared by IEC technical committee 56:
Dependability.
The text of this standard is based on the following documents:

INTRODUCTION
Obsolescence affects all products and it impacts upon all stages of their life. The term
product includes
• capital equipment;
• infrastructure;
• consumer durables;
• consumables;
• software products.
Obsolescence is inevitable and it cannot be avoided, but forethought and careful planning can
minimize its impact and its potential high costs. The objective of obsolescence management
is to ensure that obsolescence is managed as an integral part of design, development,
production and in-service support in order to minimize cost and detrimental impact throughout
the product life cycle.
Obsolescence presents itself in two ways:
• the item is no longer suitable for current demands, or
• the item is no longer available from the original manufacturer, e.g. due to economic
constraints.
From the user's point of view, obsolescence then manifests itself as difficulty in obtaining
supplies. If the end-user is the general public, it will be in the interest of the supplier to protect
his brand image by having a defined obsolescence policy.
Commercial-off-the-shelf (COTS) products and custom designed items, e.g. new design tools
and new production processes, tend to have a much shorter life in terms of availability and
supportability than in the past. With the increased use of commercial items in complex
products expecting to have a long life cycle, it has become essential to include obsolescence
management within programme plans from the earliest stages. Furthermore environmental
considerations have the potential to affect the use of some materials during the life of the
product and should be considered from the outset.
Obsolescence management is essential to achieve optimum cost-effectiveness throughout the
life cycle of a product. The purpose of this standard is to provide guidance on planning a cost
effective obsolescence management process that takes into account essential factors to
ensure product life cycle costs are considered and applied. Obsolescence management
should also include the maintenance of the relevant knowledge and skill base sets.
Clause 4 provides overview of the process and its relation to others.
Clauses 5, 6 and 8 give guidance on management responsibility, resources, measurement
and improvement with regard to obsolescence management.
Clause 7 gives guidance on planning, strategies and options described for hardware
(including integral software).
Clause 9 gives guidance on planning, strategies and options for software that is separable
from its hardware.
