16、ational 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 organization to deal with particular fie
17、lds 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 technology, ISO and IEC have established a
18、joint technical committee, ISO/IEC JTC 1. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of document should be noted. This docume
19、nt was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility 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
20、 all such patent rights.

23、IEC TS 24748-6:2016(E) Introduction This document was developed in response to a need for consistent terminology, definitions and guidance that elaborates the area of system integration, taking into account the context of use and the proven practices for the development of systems. ISO/IEC/IEEE 1528
24、8 includes an integration process that focuses on physically assembling the implemented system elements composing a system to obtain an “integrated system”. This process interfaces directly to other technical processes and indirectly to activities and tasks of other technical processes, in particula
25、r, the processes that define the system requirements, architecture and design. The purpose of this document is to facilitate the usage of the integration process of the latest revision of ISO/IEC/IEEE 15288 by providing guidance on system integration. This document describes the integration engineer
26、ing activities dealing with planning, performing and managing the integration of a system, including the related activities of other technical processes, in particular, verification and validation processes. These are real practices in industry, i.e. the integration of a system is technically engine
27、ered and managed as a project (included in the system development project). Although these practices are performed, they were not formalized in a standard or a guide when this document was written.vi ISO/IEC 2016 All rights reserved PD ISO/IEC TS 24748-6:2016 Systems and software engineering Life cy
28、cle management Part 6: System integration engineering 1 Scope This document specifies activities and processes to be implemented for engineering the integration of systems-of- interest throughout the life cycle (systems made of products and/or services; see Note 1), provides guidance for the integra
29、tion process and its relationships to other system life cycle processes as described in ISO/IEC/IEEE 15288, specifies the information items to be produced through the implementation of the integration engineering (integration process and its relationships to other system life cycle processes), speci
30、fies the contents of the information items, and provides guidelines for the format of the information items. This document can be applied to those who use or plan to use ISO/IEC/IEEE 15288 on projects dealing with man-made systems, software-intensive systems, products and services related to those s
31、ystems, regardless of project scope, methodology, size or complexity, and anyone performing integration engineering activities to aid in ensuring that the application of the integration process and its relationships to other system life cycle processes conform to ISO/IEC/ IEEE 15288. NOTE 1 Systems
32、concerned within this document are those as defined in ISO/IEC/IEEE 15288, i.e. systems that are man-made and can be configured with one or more of the following: hardware, software, data, humans, processes (e.g. processes for providing service to users), procedures (e.g. operator instructions), fac
33、ilities, materials and naturally occurring entities. NOTE 2 This document is intended to be consistent with the other parts of ISO/IEC 24748. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this do
