6、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 organization to deal with particular fields of technical activity. ISO and IEC tec
7、hnical 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/IEC JTC 1.
8、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 bodies for
9、 voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. In other circumstances, particularly when there is an urgent market requirement for such documents, the joint technical committee may decide to publish an ISO/IEC Technical Spe
10、cification (ISO/IEC TS), which represents an agreement between the members of the joint technical committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting a vote. An ISO/IEC TS is reviewed after three years in order to decide whether it will be confi
11、rmed for a further three years, revised to become an International Standard, or withdrawn. If the ISO/IEC TS is confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an International Standard or be withdrawn. Attention is drawn to the possibili
12、ty 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/IEC TS 15504-10 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 7, Software
13、 and systems engineering. ISO/IEC 15504 consists of the following parts, under the general title Information technology Process assessment: Part 1: Concepts and vocabulary Part 2: Performing an assessment Part 3: Guidance on performing an assessment Part 4: Guidance on use for process improvement an

16、nd software do not currently provide a sufficient basis for performing a process capability assessment of processes with respect to the development of complex safety-related systems. This part of ISO/IEC 15504 provides a general framework in which assessments can take place. However, additional guid
17、ance and processes are needed to support the use of the existing process assessment models for systems and software when applied to safety-related systems development in order to make consistent judgment regarding process capability or improvement priorities. Developing safety-related systems requir
18、es specialized processes, techniques, skills and experience. Process amplifications are needed in the area of safety management, safety engineering and the safety qualification. This part of ISO/IEC 15504 presents these amplifications (a safety extension) as three process descriptions. This part of
19、ISO/IEC 15504 also provides additional informative components concerning additional life-cycle verification activities related to the methods and techniques selected relevant to safety requirements adopted and tailoring guidance for users intending to use the safety extension as part of a process as
20、sessment. This part of ISO/IEC 15504, as a standalone document, can be used in conjunction with ISO/IEC 15504-5 and/or ISO/IEC TR 15504-6 process assessment models by experienced assessors with minimal support from safety domain experts. This part of ISO/IEC 15504 is developed independent of any spe
21、cific safety standards that define safety principles, methods, techniques and work products. However, elements of relevant safety standards can be mapped to the safety extension and the safety extension is intended to be extendable to include specific safety standards requirements. NOTE According to
22、 the purpose of ISO/IEC 15504, this part is to be considered independent of any domain-specific standard. Consequently, technical engineering solutions and methods as well as specific working products required by any domain-specific safety standard are not explicitly mapped on the safety engineering
23、 process and the other processes defined in this part of ISO/IEC 15504. At assessment time, these technical engineering solutions and methods, as well as specific working products, are to be considered by the assessor as project-specific solutions/choices or project requirements related to specific
24、corresponding processes.
