In software engineering, software configuration management (SCM or S/W CM; also expanded as source configuration management process and software change and configuration management^[1]) is the task of tracking and controlling changes in the software, part of the larger cross-disciplinary field of configuration management.^[2] SCM practices include revision control and the establishment of baselines. If something goes wrong, SCM can determine the "what, when, why and who" of the change. If a configuration is working well, SCM can determine how to replicate it across many hosts.
