As requirements and other factors change, the software must evolve: defects are uncovered, operating environments change, and new user requirements surface. The maintenance phase of the life cycle begins after a warranty period or after delivery of post-implementation support, while maintenance activities can occur earlier. Acceptance of DevOps has led organizations to place more weight on evolving software continuously while keeping it operating smoothly.[^s1] The Guide's top-level topics for this knowledge area are: - Software Maintenance Fundamentals - Key Issues in Software Maintenance - Software Maintenance Processes - Software Maintenance Techniques - Software Maintenance Tools Maintenance standards listed in the Guide's appendix include [[work_ieee_14764_2021_9690129|ISO/IEC/IEEE 14764:2021]].[^s1] /concepts/software-maintenance.html en zh en theme One knowledge area of SWEBOK Guide v4.0a. 2 2026-11-02T01:19:48+08:00 当前版本 true /en/concepts/software-maintenance/at/2.html en zh en concept_kind Concept kind Theme aliases Aliases 软件维护 scope_note Scope note One knowledge area of SWEBOK Guide v4.0a. 1 50 1 1
