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

16、and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/

17、IEC JTC 1. International Standards are drafted 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

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

20、 edition with IEEE Std 1219-1998. ISO/IEC JTC 1/SC 7 and the IEEE Computer Society cooperated in this project to merge the two standards.

This International Standard provides guidanc

22、e 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 Maintenance Process contains the activities and tasks of the maintainer. This Internati

23、onal 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 Standard come from ISO/IEC 12207. The mandatory clauses contain shalls and each sha

24、ll 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 harmonization of ISO/IEC 14764 and IEEE Std 1219-1998.1Because maintenance consum

25、es 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 acceptance. Therefore, a maintenance effort is needed to cope with these problems. T

26、his 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 databases, as well as when modifications are made to external software and systems interf

27、aces. 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 perform the activities and tasks in the Software Maintenance Process since these

28、 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 this International Standard. Clause 2 provides conformance information. Clause 3 p

29、rovides 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 execution considerations for the Maintenance Process. Clause 8 provides the software ma

30、intenance 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. Annex C provides a bibliography. Notice to users Errata Errata, if any, for this and all other standa
