    <body>成功的开发交付满足用户需求的软件。需求和其他因素变化后，软件必须演化：缺陷被发现，运行环境改变，新的用户需求出现。生存周期中的维护阶段在保修期之后或实现后支持交付之后开始，维护活动则可以更早发生。DevOps 的接受使组织更重视在保持平稳运行的同时持续演化软件。[^s1]&#xA;&#xA;&#xA;该知识域在指南中的一级主题为：&#xA;&#xA;- 软件维护基础&#xA;- 软件维护中的关键问题&#xA;- 软件维护过程&#xA;- 软件维护技术&#xA;- 软件维护工具&#xA;&#xA;指南附录列出的维护标准包括 [[work_ieee_14764_2021_9690129|ISO/IEC/IEEE 14764:2021]]。[^s1]</body>
