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

IEC 60300-3-6 (1997). This edition constitutes a technical revision.

This edition includes the following significant technical changes with regard to the previous

edition:
a) structural and terminological alignment with ISO;
b) focus on system processes;

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).

Software consists of information and is generally intangible and can be in the form of approaches, transactions or

procedures.

Hardware is generally tangible and its amount is a countable characteristic. Processed materials are generally

tangible and their amount is a continuous characteristic. Hardware and processed materials often are referred to as

goods.
NOTE 3 Quality assurance is mainly focussed on intended product.
[ISO 9000, definition 3.4.2]

NOTE 4 In the context of dependability, a product may be simple (e.g. a device, a software algorithm) or complex

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.
