Dependa
26、bility 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
27、 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 plannin
28、g and implementation of dependability activities throughout the life cycle of items. Dependability has a strong impact on the users perception of the value of an item developed or provided by an organization. Poor dependability will affect an organizations capability to deliver its objectives and re
29、duce 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 dependa
30、bility 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 fo
31、cuses 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
32、“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 inten
33、ded 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, busine
34、ss enterprises, and non-profit associations. BS EN 60300-1:2014IEC 60300-1:2014 IEC 2014 7 DEPENDABILITY MANAGEMENT Part 1: Guidance for management and application 1 Scope This part of IEC 60300 establishes a framework for dependability management. It provides guidance on dependability management of
35、 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 requi
36、rements 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 standard is not intended for the purpose of certification. 2 Normative references The following documents, in whole
37、 or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies.

38、ions For the purposes of this document, the following terms and definitions apply. 3.1 Terms and definitions 3.1.1 availability ability to be in a state to perform as required Note 1 to entry: Availability depends upon the combined characteristics of the reliability, recoverability and maintainabili
39、ty of the item, and in some cases, on the maintenance support performance. Note 2 to entry: Availability may be quantified using appropriate performance measures.

Note 2 to entry: The sy
44、stem elements include the organizations structure, roles and responsibilities, planning, procedures and processes. 3.1.6 dependability plan set of scheduled activities to achieve dependability objectives and targets for an item 3.1.7 dependability programme coordinated set of plans that describe the
45、 activities that lead to cost-effective achievement of dependability objectives and targets and the way they are resourced 3.1.8 item subject being considered Note 1 to entry: The item may be an individual part, component, device, functional unit, equipment, subsystem, or system. Note 2 to entry: Th
46、e item may consist of hardware, software, people or any combination thereof. Note 3 to entry: The item is often comprised of elements that may each be individually considered.
