ISO/IEC 26555:2015涉及产品线内软件产品、软件服务、软件密集型系统（包括系统架构，不包括硬件）的技术管理工具和方法。本国际标准的范围如下: ? 使本标准的用户能够全面理解、采用和实施产品线技术管理的过程、工具和方法。此外，本国际标准帮助用户根据业务和用户相关标准评估和选择相关工具和方法。 ? 帮助产品线工程师、开发人员和工具供应商了解从技术方面支持产品线实施所需的工具和方法的功能。 ? 提供特定于产品线的流程以及技术管理工具和方法的能力。 ISO/IEC 26555:2015不涉及单一系统技术管理工具和方法的过程和能力，而是涉及属于一系列系统的工具和方法。 注:系统架构是用于在给定环境中完成任务的一组逻辑和物理原则。从系统架构衍生出的组件可以是子系统、软件产品、基于人的产品（如乘员或操作员）或硬件产品（如机械结构、电子板、化学品等）。国际标准的范围从系统扩展到子系统和软件产品。其他类型的组件，尤其是与人类和硬件部件相关的组件不在本国际标准的范围内。

ISO/IEC 26555:2015 deals with the tools and methods of technical management for software products, software services, software-intensive systems (including 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 International 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. ISO/IEC 26555:2015 does not concern processes and capabilities of tools and methods for technical management for a one-of-a-kind system but rather deals with those belonging to a family of systems. NOTE: System Architecture is a set of logical and physical principles used to achieve a mission within a given environment. From System Architecture are derived components that can be subsystems, software products, human-based products like crew or operators or hardware product like mechanical structures, electronic boards, chemicals, etc. The scope of the International Standard spans from the system, to sub-systems, and software products. Other types of components and especially those related to human beings and to hardware parts are not within the scope of this International Standard.
