标准摘要
[中文适用范围]： 本文件在软件和系统产品线可变性机制的背景下： — 提供与软件和系统产品线可变性机制相关的术语和定义； — 定义在产品线生命周期的每个阶段操作可变性机制的过程及其子过程，以及提供管理支持的过程。这些过程以目的、输入、任务和结果的形式描述； — 定义支持每个过程定义任务的方法能力； — 定义自动化/半自动化任务或定义方法能力的工具能力。 本文件不涉及单一系统的过程和工具及方法的能力，而是处理产品家族的过程和能力。 [外文原描述]： ISO/IEC 26557:2016, within the context of tools and methods of variability mechanisms for software and system product lines: - provides the terms and definitions related to variability mechanisms for software and systems product lines; - defines processes and their subprocesses for operating variability mechanisms at each product line life cycle stages and those for providing managerial supports. Those processes are described in terms of purpose, inputs, tasks and outcomes; - defines method capabilities to support the defined tasks of each process; - defines tool capabilities to automate/semi-automate tasks or defined method capabilities. ISO/IEC 26557:2016 does not concern processes and capabilities of tools and methods for a single system, but rather deals with those for a family of products.
