系统和软件工程软件生命周期过程第2部分:ISO/IEC/IEEE 12207:2017和ISO/IEC 12207:2008之间的关系和映射

[中文适用范围]： 本文件提供了在ISO/IEC/IEEE 12207:2017和ISO/IEC 12207:2008中软件生命周期过程之间对应关系的表达。这些关系通过映射表展示，该映射表展示了活动、任务和过程结果之间的联系。此映射有助于使用ISO/IEC 12207:2008的用户过渡到使用ISO/IEC/IEEE 12207:2017。本文件将帮助用户理解两个版本之间的参考流程和要求的差异，以及在寻求符合ISO/IEC/IEEE 12207:2017时可能存在的差距或过程改进。此外，本文件还向用户提供映射关系，以帮助识别ISO/IEC/IEEE 12207:2017中软件系统的对应流程结果、活动和任务。本文件对ISO/IEC/IEEE 12207:2017与ISO/IEC 12207:2008之间的映射可以作为依据，以持续开展、改进和发展基于ISO/IEC 12207:2008的现有流程资产（包括软件特定流程资产），从而有效实施ISO/IEC/IEEE 12207:2017。这些活动和任务可以迭代应用。 [外文原描述]： This document provides the mapping expressing corresponding relations between software life cycle processes in ISO/IEC/IEEE 12207:2017 and the processes in ISO/IEC 12207:2008. These relations are demonstrated by means of mapping tables that show relationships between activities and tasks, and process outcomes. This mapping assists users of ISO/IEC 12207:2008 to transition to using ISO/IEC/IEEE 12207:2017. This document will help users understand the differences between the reference processes and requirements of the two editions of ISO/IEC/IEEE 12207, and any potential gaps or process enhancements that can be needed in seeking conformance to and/or using ISO/IEC/IEEE 12207:2017. Also, this document provides to such users the mapping which helps to identify corresponding process outcomes, activities and tasks of processes for software systems in ISO/IEC/IEEE 12207:2017. The mapping between ISO/IEC/IEEE 12207:2017 and ISO/IEC 12207:2008 in this document can be used as a basis to continuously conduct, improve and extend current process assets including software specific process assets based on ISO/IEC 12207:2008 for effective implementation of ISO/IEC/IEEE 12207:2017. These process activities and tasks can be applied iteratively.
