15、al 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 through technical committees established by

16、 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 nongovernmental, in liaison with ISO and IEC, also take part in the work. In the field of

17、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 (IEEESA) Standards Board. The IEEE develops its standards thro

18、ugh 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 Institute and serve without compensation. While the IE

19、EE 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 Standards are drafted in accordance with the rules giv

20、en in the ISO/IEC Directives, Part 2. 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 existence or validity of any patent rights in co

21、nnection therewith. ISO/IEC and IEEE are 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 licensing terms or conditions provided in

22、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 nondiscriminatory. Users of this standard are expressly advised that determination of the validity of any patent rights, and the risk of

23、infringement of such rights, is entirely their own responsibility. Further information may be obtained from ISO or the IEEE Standards Association. ISO/IEC 15939 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 7, Systems and software engineering, in co

24、operation with the Software by an acquirer (or thirdparty agents) for evaluating conform ance of the suppliers measurement process to this document; by an acquirer (or thirdparty agents) to implement a measure ment process to address specific technical and project management information requirements

25、 related to the acquisition; in a contract between an acquirer and a supplier as a method for defining the process and product measurement information to be exchanged. INTERNATIONAL STANDARD ISO/IEC/IEEE 15989:2017(E) Systems and software engineering Measurement process 1 Scope This document establi

26、shes a common process and framework for measurement of systems and software. It defines a process and associated terminology from an engineering viewpoint. The process can be applied to the project and products across the life cycle. The measurement process can be applied throughout the life cycle t

27、o aid the planning, managing, assessing, and decisionmaking in all stages of a system or software life cycle. This document also provides activities that support the definition, control and improvement of the measurement process used within an organization or a project. This document does not assume

28、 or prescribe an organizational model for measurement. The user of this document decides, for example, whether a separate measurement function is necessary within the organization and whether the measurement function should be integrated within individual projects or across projects, based on the cu

29、rrent organizational structure, culture and prevailing constraints. This document does not prescribe a specific set of measures, method, model or technique. The users of this document are responsible for selecting a set of measures for the project and defining the application of those measures acros

30、s the process, products, and other elements of the life cycle. The parties are also responsible for selecting and applying appropriate methods, models, tools and techniques suitable for the project. This document is not intended to prescribe the name, format, explicit content, or recording media of

31、the information items to be produced. This document does not imply that documents be packaged or combined in some fashion. These decisions are left to the user of this document. ISO/IEC/IEEE 15289 addresses the content for life cycle process information items (documentation). The measurement process

32、 is supposed to be appropriately integrated with the organizational quality system. Not all aspects of internal audits and noncompliance reporting are covered explicitly in this document as they are assumed to be in the domain of the quality system. This document is not intended to conflict with any

33、 organizational policies, standards or procedures that are already in place. However, any conflict should be resolved and any overriding conditions and situations need to be cited in writing as exceptions to the application of this document. 2 Normative references There are no normative references i
