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 particular fields of technical activity. ISO and IEC technical committees collaborate in fi

In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted

10、 in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an Internat

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/

12、IEC/IEEE 14764 was prepared by Joint Technical Committee ISO/IEC JTC 1, Subcommittee SC 7, (Software and System Engineering). The first edition of ISO/IEC 14764 was prepared by ISO/IEC JTC 1/SC 7. The current edition is the result of merging the original edition with IEEE Std 1219-1998. ISO/IEC JTC

13、1/SC 7 and the IEEE Computer Society cooperated in this project to merge the two standards. This second edition cancels and replaces the first edition (1999).

14、are Life Cycle ProcessesMaintenance. This International Standard provides guidance on the Software Maintenance Process. Software Maintenance is a primary process in the life cycle of a software product, as described in ISO/IEC 12207, “Information technology Software life cycle processes.” The Mainte

15、nance Process contains the activities and tasks of the maintainer. This International Standard is part of the ISO/IEC 12207 family of documents. In this International Standard, ISO/IEC 12207 refers to ISO/IEC 12207:1995 as amended in 2002 and 2004. The only mandatory clauses in this International St

16、andard come from ISO/IEC 12207. The mandatory clauses contain shalls and each shall from ISO/IEC 12207 that is duplicated in this International Standard is boxed. The related ISO/IEC 12207 clause number is listed after the boxed ISO/IEC 12207 shalls. This International Standard is the result of the

17、harmonization of ISO/IEC 14764 and IEEE Std 1219-1998.1Because maintenance consumes a major share of a software life cycle financial resources, it should be an important project consideration. During operation of the software, problems may be detected that were not detected during validation and acc

18、eptance. Therefore, a maintenance effort is needed to cope with these problems. This maintenance effort also covers software improvements needed to meet new or modified user requirements. Software maintenance is commonly needed when upgrading system components, such as operating systems and database

19、s, as well as when modifications are made to external software and systems interfaces. Software maintenance may be a significant portion of life cycle costs. Software maintainers use a number of specific tools, methods, and techniques. This International Standard does not specify how to implement or

20、 perform the activities and tasks in the Software Maintenance Process since these are dependent upon the formal agreement and organizational requirements. Maintenance is required on all types of software, whatever the technology, technique, or tool used to create it. Clause 1 provides the scope of t

21、his International Standard. Clause 2 provides conformance information. Clause 3 provides normative references. Clause 4 provides terms and definitions. Clause 5 provides the application of this International Standard. Clause 6 provides the details of the Maintenance Process. Clause 7 provides execut

22、ion considerations for the Maintenance Process. Clause 8 provides the software maintenance strategy. Annex A provides a cross reference between clauses in this International Standard and ISO/IEC 12207. Annex B provides a list of abbreviations used in this International Standard.

41、cribed in ISO/IEC 12207, including Amendments. This International Standard also establishes definitions for the various types of maintenance. This International Standard provides guidance that applies to planning, execution and control, review and evaluation, and closure of the Maintenance Process.

42、The scope of this International Standard includes maintenance for multiple software products with the same maintenance resources. “Maintenance” in this International Standard means software maintenance unless otherwise stated. 1.1 Scope This standard describes an iterative process for managing and e

43、xecuting software maintenance activities. Use of this standard is not restricted by size, complexity, criticality, or application of the software product. This standard uses a process model to discuss and depict each phase of software maintenance. The criteria established apply to both the planning

44、of maintenance for software while under development, as well as the planning and execution of software maintenance activities for existing software products. Ideally, maintenance planning should begin during the stage of planning for software development. This International Standard provides the fra

45、mework within which generic and specific software maintenance plans may be executed, evaluated, and tailored to the maintenance scope and magnitude of given software products. This International Standard provides the framework, precise terminology, and processes to allow the consistent application o

46、f technology (tools, techniques, and methods) to software maintenance. This International Standard provides guidance for the maintenance of software. The basis for the Maintenance Process and its activities comes from the definitions of ISO/IEC 12207. It defines the activities and tasks of software

47、maintenance, and provides maintenance planning requirements. It does not address the operation of software and the operational functions, e.g., backup, recovery, system administration, which are normally performed by those who operate the software. This International Standard is written primarily fo

48、r maintainers of software and additionally for those responsible for development and quality assurance. It may also be used by acquirers and users of systems containing software who may provide inputs to the maintenance plan. 1.2 Purpose This International Standard provides guidance on the managemen

49、t of (or how to perform) the Maintenance Process. It identifies how the Maintenance Process can be invoked during acquisition and operation. This lnternational Standard also emphasizes the following in the Maintenance Process: the maintainability of software products; the need for maintenance service models; and the need for a maintenance strategy and plan. 1.3 Field of application This International Standard is intended to provide guidance for the planning for and maintenance of software products or services, whether performed internally or externally
