Dependability management - Part 1: Guidance for management and application

IEC 60300-1:2014 establishes a framework for dependability management. It provides guidance on dependability management of products, systems, processes or services involving hardware, software and human aspects or any integrated combinations of these elements. It presents guidance on planning and implementation of dependability activities and technical processes throughout the life cycle taking into account other requirements such as those relating to safety and the environment. This standard gives guidelines for management and their technical personnel to assist them to optimize dependability. This third edition cancels and replaces the second edition published in 2003 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- an updating of definitions to reflect IEC 60050-191:2014;
- an enhanced description of dependability and its attributes;
- a more generic approach to dependability management;
- revised guidelines for application of dependability management;
- a more generic approach to the life cycle;
- a framework for dependability standards. Keywords: dependability management

DEPENDABILITY MANAGEMENT –
Part 1: Guidance for management and application
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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

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 60300-1 has been prepared by IEC technical committee 56:

Dependability.

This bilingual version (2014-08) corresponds to the English version, published in 2014-05.

This third edition cancels and replaces the second edition published in 2003 and constitutes a

edition:
a) an updating of definitions to reflect IEC 60050-191:2014;
b) an enhanced description of dependability and its attributes;
c) a more generic approach to dependability management;
d) revised guidelines for application of dependability management;

INTRODUCTION

This part of IEC 60300 describes the processes involved in managing dependability within an

organization and establishes a framework for managing dependability activities for the

purpose of achieving dependability performance.

Dependability is the ability of an item to perform as and when required. Dependability is a

term used to describe the time-dependent characteristics associated with the performance of

an item. Dependability includes characteristics such as availability, reliability, maintainability

and supportability under given conditions of use and maintenance support requirements.

Dependability describes the extent to which something can be trusted to behave as expected.

Dependability creates trust and confidence and affects the ability of an organization to meet

its objectives. It is achieved by effective planning and implementation of dependability

activities throughout the life cycle of items.

Dependability has a strong impact on the user’s perception of the value of an item developed

or provided by an organization. Poor dependability will affect an organization’s capability to

deliver its objectives and reduce its reputation.

Dependability management provides a systematic approach for addressing dependability and

related issues from an organizational and business perspective. Dependability is often driven

by technology and requires the integration of innovation with legacy products. Achieving

dependability throughout the life cycle process can be influenced by market dynamics, global

economics and resource distributions, changing customer needs, and a competitive

environment. Strategies need to adapt to anticipated changes to sustain viability in business

operations. Dependability management focuses on the needs of stakeholders in optimizing

dependability to enhance organizational objectives and return-on-investments.

This standard is written specifically for application to technological products, systems,

processes and services, which are referred to in this standard by the general term “item”.

However, much of the guidance provided is generic and can be adapted for application in

various non-technological applications. In addition, the potential side effects on safety,

environment and other factors should be identified, analysed and managed when optimizing

dependability.

The intended audience for this standard ranges from users, owners and customers to

organizations involved in and responsible for ensuring dependability requirements are being

met. Organizations include all types and sizes of corporations, public and private institutions

such as in government agencies, business enterprises, and non-profit associations.
