40、Standardization) and IEC (the 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 orga
41、nization to deal with particular fields of technical activity. ISO 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 technol
42、ogy, ISO and IEC have established a joint technical committee, ISO/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
43、adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subjec
44、t of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 26514 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 7, Software and systems engineering. BS ISO/IEC 26514:2008 BS ISO/IEC 26514:2008
45、 ISO/IEC 26514:2008(E) ISO/IEC 2008 All rights reserved ix Introduction Anyone who uses application software needs accurate information about how the software will help the user accomplish a task. The documentation may be the first tangible item that the user sees and therefore influences the users
46、first impressions of the software product. If the information is supplied in a convenient form and is easy to find and understand, the user can quickly become proficient at using the product. Hence, well-designed documentation not only assists the user and helps to reduce the cost of training and su
47、pport, but also enhances the reputation of the product, its producer, and its suppliers. Although software developers aim to design user interfaces that behave so intuitively that very little separate documentation is needed, this is rarely possible. Todays software offers increasingly robust functi
48、onality, not only within applications, but also across applications that intelligently exchange information with one another. Further, most software designs include underlying rules and calculations, or algorithms, that affect the results a user can obtain when using the software. Such underlying pr
49、ogramming mechanics are discernable by users, but only through laborious testing. For these reasons and more, user documentation remains an essential component of usable software products. Documentation is often regarded as something done after the software has been implemented. However, for high-quality software documentation, its development should be regarded as an integral part of the software life cycle process. If done properly, documentation or information management is a big
