DEPENDABILITY MANAGEMENT –
Part 2: Guidelines for dependability management
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 60300-2 has been prepared by IEC technical committee 56:
Dependability.
This second edition cancels and replaces the first edition, published in 1995, as well as

INTRODUCTION
Dependability deals with the availability performance of a product. The factors influencing
availability performance are reliability, maintainability and maintenance support performance.
Dependability is a technical discipline that needs to be managed in order to achieve its
objectives and benefits. Dependability management should provide a clear customer focus. It
should be incorporated into an organization’s overall management system to coordinate
dependability activities for cost-effective results.
This part of IEC 60300 provides guidelines on dependability management. It supports the top-
level dependability management system standard IEC 60300-1 by identifying and referencing
relevant processes and methods for a broad range of products. This standard links the
management process steps with applicable dependability standards to foster continual
improvement.
The concept of product life cycle is introduced to deal with the significance of dependability
activities and timing for their effective implementation. The association of product life cycle
phases with the applicable dependability programme elements and tasks are presented to
facilitate tailoring of dependability programmes to meet specific project needs.
This standard outlines the generic process for dependability applications based on
successfully applied industry practices. It can be incorporated into the management systems
of large corporations as well as being adaptable to small businesses.
Time-dependent reliability, maintainability and maintenance support performance
characteristics in products are addressed.
This standard references other published TC 56 standards and also makes reference to
several ISO/IEC standards as well as some sector specific reliability standards. These
references are listed in the bibliography.
Annex A provides a summary description of the elements and tasks of a dependability
programme for application.
Annex B defines the product life cycle phases.
Annex C presents an association of product life cycle phases with the applicable
dependability elements and tasks.
Annex D presents process steps and standards for managing dependability.
Annex E provides a list of questions to facilitate dependability management review.
Annex F provides guidelines for the tailoring process.
Annex G presents the classification of dependability standards with the life cycle phases.

DEPENDABILITY MANAGEMENT –
Part 2: Guidelines for dependability management
1 Scope
This part of IEC 60300 provides guidelines for dependability management of product design,
development, evaluation and process enhancements. Life cycle models are used to describe
product development or project phases. A tailoring process is recommended for the selection
of relevant dependability programme tasks for time-phased implementation to meet varied
user needs.
This part of IEC 60300 is applicable for detailed planning and implementation of a
dependability programme to meet specific product needs. The tailoring process provides a
method for selection of dependability programme elements and associated processes from a
product or project perspective. This standard is applicable to all organizations, during all life-
cycle phases and in any contract situation, regardless of type, size and product provided.

NOTE 1 There are four generic product categories, as follows:
– services (e.g. transport);
– software (e.g. computer program, dictionary);
– hardware (e.g. engine mechanical part);
– processed materials (e.g. lubricant).
Many products comprise elements belonging to different generic product categories. Whether the product is then
called service, software, hardware or processed material depends on the dominant element. For example, the
offered product "automobile" consists of hardware (e.g. tyres), processed materials (e.g. fuel, cooling liquid),
software (e.g. engine control software, driver's manual), and service (e.g. operating explanations given by the
salesman).
NOTE 2 Service is the result of at least one activity necessarily performed at the interface between the supplier
and customer and is generally intangible. Provision of a service can involve, for example, the following:
– an activity performed on a customer-supplied tangible product (e.g. automobile to be repaired);
– an activity performed on a customer-supplied intangible product (e.g. the income statement needed to prepare
a tax return);
– the delivery of an intangible product (e.g. the delivery of information in the context of knowledge transmission);
– the creation of ambience for the customer (e.g. in hotels and restaurants).

4 Dependability management system
The dependability management system is part of the overall management system of an
organization. It provides an organizational framework for strategic direction of dependability
policy, control of dependability functions and coordination of all dependability activities. Early
attention to dependability plans and allocation of appropriate resources is needed for tailoring
of effort to achieve the desired dependability objectives. To ensure dependability of a product,
it is essential that reliability and maintainability are designed into the product and verified for
their acceptance at various stages of the product realization process. Appropriate
maintenance support effort is needed to sustain dependability in product applications, where
available technology does not allow failure-free life cycles.
The dependability management system should provide a product life cycle framework for
implementation of appropriate dependability programmes (see 3.3, Note 2) to meet the
organization’s business objectives, including customer satisfaction. The product life cycle
reflects an end-to-end process; from product inception through development and operation to
its end-of-life or withdrawal from use. The life cycle process provides a useful framework to
group related dependability programme elements and tasks.
The process steps for managing dependability are presented in the top-level dependability
management standard IEC 60300-1. They include:
– defining dependability objectives;
– analysis of the scope of dependability work needed and implications;
– planning strategy and activities to achieve dependability objectives;
– implementation of selected dependability tasks;
– analysis of results of dependability tasks implemented;
– evaluation of achieved dependability results for further improvement.
A typical process flow diagram is shown in Figure 1. The applicable dependability standards
associated with each process step are presented in Annex D.
