This text discusses software change management (SCM), a standard practice in software development that provides a framework to track, test, and deploy changes safely. SCM helps teams stay in control of updates by providing greater visibility and control over changes, reducing the risk of uncontrolled changes, security vulnerabilities, and production failures. It ensures every update is reviewed, tested, and approved with security, stability, and cross-team impact in mind. By implementing structured processes for managing changes, teams can minimize risks, ensure smooth collaboration between Dev, Ops, and Security, and deliver internal apps 10x faster. The text also explains various change management models, such as ITIL, Agile, and DevOps, and provides best practices for faster, safer, and more predictable software releases.
