23、International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particul

24、ar fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and nongovernmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have establish

25、ed a joint technical committee, ISO/IEC JTC 1. IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Association (IEEESA) Standards Board. The IEEE develops its standards through a consensus development process, approved by t

26、he American National Standards Institute, which brings together volunteers representing varied viewpoints and interests to achieve the final product. Volunteers are not necessarily members of the Institute and serve without compensation. While the IEEE administers the process and establishes rules t

27、o promote fairness in the consensus development process, the IEEE does not independently evaluate, test, or verify the accuracy of any of the information contained in its standards. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/I

28、EC Directives, Part 1. In particular, the different approval criteria needed for the different types of document should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility tha

29、t some of the elements of this document may be the subject of patent rights. ISO, IEC, and IEEE shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO li

30、st of patent declarations received (see www.iso.org/patents). Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.

This document was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 7, Syst

32、ems and software engineering, in cooperation with the IEEE Computer Society Systems and Software Engineering Standards Committee, under the Partner Standards Development Organization cooperation agreement between ISO and IEEE. This first edition of ISO/IEC/IEEE 12207 cancels and replaces ISO/IEC 122

33、07:2008 (second edition), which has been technically revised. Changes in this revision of ISO/IEC/IEEE 12207 were developed in conjunction with a corresponding revision of ISO/IEC/IEEE 15288:2015, Systems and software engineering System life cycle processes. The purpose of these revisions is to acco

34、mplish the harmonization of the structures and contents of the two documents, while supporting the requirements of the engineering and assessment communities. This document was developed with the following goals: provide a common terminology between the revision of ISO/IEC/IEEE 15288 and ISO/IEC/IEE

35、E 12207; where applicable, provide common process names and process structure between the revision of ISO/IEC/IEEE 15288 and ISO/IEC/IEEE 12207; and enable the user community to evolve towards fully harmonized standards, while allowing backward compatibility. This revision is intended to achieve a f

36、ully harmonized view of the system and software life cycle processes. ISO/IEC/IEEE 12207:2017(E) vii ISO/IEC 2017 All rights reserved IEEE 2017 All rights reserved Introduction The complexity of software systems has increased to an unprecedented level. This has led to new opportunities, but also to

37、increased challenges for the organizations that create and utilize systems. These challenges exist throughout the life cycle of a system and at all levels of architectural detail. This document provides a common process framework for describing the life cycle of systems created by humans, adopting a

38、 Software Engineering approach. Software Engineering is an interdisciplinary approach and means to enable the realization of successful software systems. It focuses on defining stakeholder needs and required functionality early in the development cycle, documenting requirements, and performing desig

39、n synthesis and system validation while considering the complete problem. It integrates all the disciplines and specialty groups into a team effort forming a structured development process that proceeds from concept to production to operation and maintenance. It considers both the business and the t

40、echnical needs of all stakeholders with the goal of providing a quality product that meets the needs of users and other applicable stakeholders. This life cycle spans the conception of ideas through to the retirement of a system. It provides the processes for acquiring and supplying systems. It help

41、s to improve communication and cooperation among the parties that create, utilize and manage modern software systems in order that they can work in an integrated, coherent fashion. In addition, this framework provides for the assessment and improvement of the life cycle processes. The processes in t

42、his document form a comprehensive set from which an organization can construct software life cycle models appropriate to its products and services. An organization, depending on its purpose, can select and apply an appropriate subset to fulfill that purpose. This document can be used in one or more

43、of the following modes: a) By an organization to help establish an environment of desire d processes. These processes can be supported by an infrastructure of methods, procedures, techniques, tools and trained personnel. The organization may then employ this environment to perform and manage its pro

44、jects and progress software systems through their life cycle stages. In this mode, this document is used to assess conformance of a declared, established environment to its provisions. b) By a project to help select, structure and employ the element s of an established environment to provide product

45、s and services. In this mode, this document is used in the assessment of conformance of the project to the declared and established environment. c) By an acquirer and a supplier to help develop an agreement co ncerning processes and activities. Via the agreement, the processes and activities in this

46、 document are selected, negotiated, agreed to and performed. In this mode, this document is used for guidance in developing the agreement. d) By process assessors to serve as a process reference model fo r use in the performance of process assessments that may be used to support organizational proce

47、ss improvement. INTERNATIONAL STANDARD ISO/IEC/IEEE 12207:2017(E) 1 ISO/IEC 2017 All rights reserved IEEE 2017 All rights reserved Systems and software engineering Software life cycle processes 1 Scope 1.1 Overview This document establishes a common framework for software life cycle processes, with

48、welldefined terminology, that can be referenced by the software industry. It contains processes, activities, and tasks that are applicable during the acquisition, supply, development, operation, maintenance or disposal of software systems, products, and services. These life cycle processes are accom

49、plished through the involvement of stakeholders, with the ultimate goal of achieving customer satisfaction. This document applies to the acquisition, supply, development, operation, maintenance, and disposal (whether performed internally or externally to an organization) of software systems, products and services, and the software portion of any system, Software includes the software portion of firmware. Those aspects of system definition needed to provide the context for softwar
