ISO/IEC 26553:2018本文件在软件和系统产品线详细设计和实施的工具和方法范围内:
-提供特定于软件和系统产品线实现的术语和定义
-定义产品线实现过程中执行的过程（这些过程按照目的、输入、任务和结果进行描述）
-定义方法能力，以支持每个过程的定义任务；和
-定义自动化/半自动化任务的工具功能或定义的方法功能
本文件涉及一系列产品（而非单个系统）的实现工具和方法的过程和能力。

ISO/IEC 26553:2018 This document, within the context of tools and methods of detailed design and implementation for software and system product lines:
- provides the terms and definitions specific to realization for software and systems product lines;
- defines processes performed during product line realization (those processes are described in terms of purpose, inputs, tasks and outcomes);
- defines method capabilities to support the defined tasks of each process; and
- defines tool capabilities to automate/semi-automate tasks or defined method capabilities.
This document concerns processes and capabilities of realization tools and methods for a family of products, not for a single system.
