145 FOREWORD
146 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
147 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
148 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
149 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
150 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
151 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
152 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
153 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
154 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
155 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
156 consensus of opinion on the relevant subjects since each technical committee has representation from all
157 interested IEC National Committees.
158 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
159 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
160 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
161 misinterpretation by any end user.
162 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
163 transparently to the maximum extent possible in their national and regional publications. Any divergence between
164 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
165 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
166 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
167 services carried out by independent certification bodies.
168 6) All users should ensure that they have the latest edition of this publication.
169 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
170 members of its technical committees and IEC National Committees for any personal injury, property damage or
171 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
172 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
173 Publications.
174 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
175 indispensable for the correct application of this publication.
176 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
177 rights. IEC shall not be held responsible for identifying any or all such patent rights.
178 International Standard IEC 60300-1 has been prepared by IEC technical committee TC56.
179 Dependability
180 This fourth edition cancels and replaces the third edition published in 2014 and constitutes a
181 technical revision.
182 This edition includes the following significant technical changes with respect to the previous
183 edition:
184 a) more guidance on integration of dependability activities into an existing management
185 system;
186 b) greater detail on the activities required to establish and implement a progamme of
187 dependability activities
188 c) changes to provide consistency with revision of IEC 60300-3-4, IEC 60300-3-1, IEC 60300-
189 3-10 and IEC 60300-3-14
190 The text of this International Standard is based on the following documents:

205 INTRODUCTION
206 Dependability is the ability to perform as and when required. A dependable item is one where
207 there is justified confidence that it operates as desired and satisfies agreed stakeholder needs
208 and expectations. Dependability has many attributes but is usually characterised in terms of
209 reliability, maintainability and supportability, and the derived characteristic of availability. In
210 some cases, attributes such as resilience, recoverability, durability, integrity, safety, security,
211 and trustworthiness are included in, or overlap with, dependability.
212 The specification and verification of dependability attributes provides stakeholders with
213 assurance that requirements will be met into the future and quality will be maintained over time.
214 Dependability is an important attribute of a system, product or service which influences the
215 business strategies associated with its design, acquisition and use, and its life time costs. The
216 dependability of an organization's systems, products and services has a strong impact on the
217 perception of the value and trustworthiness of the organization.
218 Dependability is managed as a key element of an organization’s wider management system,
219 particularly aspects relating to assets, quality and finance. There should not be a separate
220 management system for dependability.
221 This document highlights the importance and benefits of managing dependability. It gives
222 guidance on dependability activities and how to integrate them into an existing management
223 system and life cycle processes. It provides information on different life cycle models and how
224 dependability activities can be incorporated into them so that an efficient, effective and
225 economical approach is achieved.
226 Dependability activities bring benefits whenever they are performed but greater benefit is
227 achieved the sooner in the life cycle they are implemented.
228 This document is applicable to a broad range of industry sectors and organizations of any size.
229 It applies to systems of systems, large unique systems, mass produced industrial and consumer
230 products, software applications, components and services. These categories are not mutually
231 exclusive. For example, many products and components are in themselves complex systems.
232 The document will be useful for:
233 • managers and technical personnel;
234 • those involved in deciding how their systems, products and services can be made
235 dependable;
236 • organizations such as regulators who evaluate the dependability of systems, products and
237 services;
238 • those (e.g. users or the public) who need justified confidence in systems, product and
239 services that might affect them;
240 • developers of other dependability related standards.
241 This document is one of a suite of "top level" interrelated IEC dependability standards that
242 provide managers and technical personnel, with guidance on how to effectively plan and
243 implement dependability activities. As such this document should be used in conjunction with:
244 • IEC 60300-3-4 which provides guidance on writing dependability requirements in
245 specifications, and on the means of assuring the achievement of those requirements;
246 • , IEC 60300-3-10 and IEC 60300-3-14 which provide guidance on how to identify and apply
247 appropriate analysis and assurance techniques for maintainability (and maintenance) and
248 supportability (and support) respectively. Standards to cover reliability and availability are
249 planned.

251
252 Part 1: Managing Dependability
253 1 Scope
254 This document provides guidance on:
255 • the meaning and significance of dependability from a business, technical and financial
256 perspective;
257 • achieving dependability through suitable adaptation of organizational management systems
258 such as those described in the ISO 9000 series (Quality management), ISO 26000
259 (Guidance on social responsibility) and the ISO 55000 series (Asset management);
260 • the activities that need to be integrated into management systems and life cycle processes
261 in order to achieve dependable systems, products and services;
262 • planning and implementing dependability activities throughout the life cycle to achieve and
263 assure required outcomes, taking into account factors such as costs, safety, the
264 environment, customer goodwill, brand and reputation.
265 This document is applicable to any type of system, both new and existing, to mass produced
266 industrial or consumer products, to components and to services. This document addresses all
267 elements of systems, products and services including hardware, software, data, processes,
268 procedures, facilities, materials, and personnel required for operations and support.
