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 o

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
28、 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 document wa

This International Standard defines how the tools and methods can su
34、pport for the software and systems product line-specific technical management processes. Since product lines deal with multiple products that have similarities, product lines have an unprecedented level of technical management complexities. This arises from the following sources: There are inherent
35、differences in technical considerations because there are parallel development processes, domain and application engineering, in a product line and the two processes are tightly related with each other around assets. The close relationships among domain engineering, application engineering, and asse
36、ts require the highly matured managerial capabilities for addressing relationships among them. There are lack of tools and methods to support the product line-specific technical management. Technical management provides management support for a timely and proper deployment of product line in balance
37、 with pre-defined product line objectives such as reusability, reducing cost, improving quality, etc., as well as its planned cost, schedule, and resources. Technical management addresses actual means used to support, monitor, and control the activities of both domain engineering and application eng
38、ineering of a product line. There are needs for defining product line-specific technical management processes that integrate the involved product line disciplines with those for a single product. Furthermore, support of tools and methods are required so that a product line organization can perform t
39、echnical management under the systematic control of complexities. This International Standard addresses the product line-specific processes in technical management by dividing those into process management, variability management, asset management, and support management areas with the guidance of a
40、 set of tools and methods capabilities for supporting tasks for product line technical management. This International Standard is intended to benefit people who acquire, supply, develop, operate, and maintain tools and methods for product line technical management. This International Standard can be
41、 used in one or more of the following modes: By an organization intended to implement product linesto understand, adopt, and enact the processes, tools, and methods for product line technical management. This also helps the organization to evaluate and select relevant tools and methods based on busi
42、ness and user-related criteria. By a tool vendor who facilitates or leverages product line engineering practicesto provide a set of tool capabilities that should be embodied in a tool for supporting product line technical management. ISO/IEC 26550 addresses both engineering and management processes
43、and covers the key characteristics of product line development. ISO/IEC 26550 provides an overview of the consecutive international standards (i.e. ISO/IEC 26551 to ISO/IEC 26556), as well as the structure of the model: Processes and capabilities of methods and tools for product line scoping, domain
44、 requirements engineering, and application requirements engineering are provided as ISO/IEC 26551. Processes and capabilities of methods and tools for domain design and application design are provided as ISO/IEC 26552. Processes and capabilities of methods and tools for domain realization and applic
45、ation realization are provided as ISO/IEC 26553. Processes and capabilities of methods and tools for domain verification and validation and application verification and validation are provided in ISO/IEC 26554. Processes and capabilities of methods and tools for technical management are provided in

47、IONAL ST ANDARD ISO/IEC 26555:2015(E) Software and systems engineering Tools and methods for product line technical management 1 Scope This International Standard deals with the tools and methods of technical management for software products, software services, software-intensive systems (including
48、System Architecture and excluding hardware) within a product line. The scope of this International Standard is as follows: Enable the users of this standard to holistically understand, adopt, and enact the processes, tools, and methods for product line technical management. In addition, this Interna
49、tional Standard helps the users evaluate and select relevant tools and methods based on business and user-related criteria. Help product line engineers, developers, and tool vendors become informed about capabilities of tools and methods that are required for supporting product line implementation from technical aspects. Provide product line-specific processes and capabilities of tools and methods in technical management. This International Standard does not concern processes and capabilities of tools and metho
