24、hts reserved v Foreword ISO (the International Organization for 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
25、 through technical committees established by the respective organization 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,
26、 also take part in the work. In the field of information technology, ISO and IEC have established 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 (IEEE-SA) Standar
27、ds Board. The IEEE develops its standards through a consensus development process, approved by the 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 Institut
28、e and serve without compensation. While the IEEE administers the process and establishes rules to 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. International Standard
29、s are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of ISO/IEC JTC 1 is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an Internation
30、al Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is called to the possibility that implementation of this standard may require the use of subject matter covered by patent rights. By publication of this standard, no position is taken with respect to the
31、existence or validity of any patent rights in connection therewith. ISO/IEEE is not responsible for identifying essential patents or patent claims for which a license may be required, for conducting inquiries into the legal validity or scope of patents or patent claims or determining whether any lic
32、ensing terms or conditions provided in connection with submission of a Letter of Assurance or a Patent Statement and Licensing Declaration Form, if any, or in any licensing agreements are reasonable or non-discriminatory. Users of this standard are expressly advised that determination of the validit
33、y of any patent rights, and the risk of infringement of such rights, is entirely their own responsibility. Further information may be obtained from ISO or the IEEE Standards Association. ISO/IEC/IEEE 23026 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee
34、SC 7, Software and systems engineering, in cooperation with the Systems and Software Engineering Standards Committee of the IEEE Computer Society, under the Partner Standards Development Organization cooperation agreement between ISO and IEEE. This first edition of ISO/IEC/IEEE 23026 replaces and su
35、persedes ISO/IEC 23026:2006, which was the adoption of IEEE Std 2001 (TM)-2002, IEEE Recommended Practice for the Internet Website Engineering, Website Management, and Website Life Cycle. The IEEE contributed IEEE Std 2001-2002 as a source for this standard. BS ISO/IEC/IEEE 23026:2015 ISO/IEC/IEEE 2
36、3026:2015(E) vi ISO/IEC 2015 All rights reserved IEEE 2015 All rights reserved Introduction The increase in use of the World Wide Web for every type of communication, and the accelerating development of new technical protocols, products, and services, for website development and hosting, have both s
37、implified and complicated the engineering and management of websites. Because of the ready availability of commercial website providers, it has become simpler for information and communications technology (ICT) enterprises of all sizes to launch websites to present technical information. The growth
38、in global communities of interest in software, systems, and services has expanded the creation of information from many sources. To a large extent, use of digital communications, particularly those accessible through the Internet or Intranets, has supplanted printed publications for conveying techni
39、cal information. This trend applies to systems and user documentation as well as to service management and operational plans, policies, and procedures. Other factors have also affected the design and operation of websites since the original publication of ISO/IEC 23026IEEE Std 2001-2002, a source fo
40、r this International Standard. The prevalence of automated search engines to locate technical information results in new considerations for website design. The increasing sophistication of information security threats to technical enterprises and their information, as well as concerns for the privac
41、y of Internet users, have markedly complicated the process of delivering ICT information over the Web. This revision of ISO/IEC 23026 therefore has increased emphasis on information security and privacy concerns. The diversity of websites for commercial marketing and social networking purposes refle
42、cts different interests and media choices from those websites that deliver ICT reference information. This revision of ISO/IEC 23026 applies primarily to websites whose purpose is to deliver information about ICT systems, software, and services. It includes increased emphasis on the human factors co
43、ncerns for making information easily retrievable and usable for the intended audience. It recommends practices for websites based on World Wide Web Consortium (W3C) and related industry guidelines, which have changed significantly since the original version of this International Standard. With rapid
44、 changes in technology, users may seek current technical guidance to fulfill the intent of this International Standard. It continues to address the entire life cycle of website strategy, design, and ongoing sustainment that are the responsibility of the website owner. BS ISO/IEC/IEEE 23026:2015 ISO/

46、r the life cycle of websites including strategy, design, engineering, testing and validation, and management and sustainment for Intranet and Extranet environments. This International Standard applies to those using web technology to present information and communications technology (ICT) informatio
47、n, such as user documentation for systems and software, life-cycle documentation for systems and software engineering projects, and documentation of policies, plans, and procedures for IT service management. This International Standard provides requirements for website owners and website providers,
48、managers responsible for establishing guidelines for website development and operations, for software developers and operations and maintenance staff who may be external or internal to the website owners organization. It applies to websites for public access and for limited access, such as for users
49、, customers, and subscribers seeking information on IT products and services. The goal of this International Standard is to improve the usability of informational websites and ease of maintenance of managed Web operations in terms of: a) locating relevant and timely information, b) applying information security management, c) facilitating ease of use, d) providing for consistent and efficient development and maintenance practices. This International Standard is not intended for websites used primarily for marketing
