Release Management
Release management is a systematic and controlled process for planning, scheduling, coordinating, and overseeing the deployment of software, applications, or IT infrastructure changes into various environments, ultimately leading to their introduction into the production environment. The primary goal of release management is to ensure the smooth and reliable delivery of software or changes to end-users or customers while minimizing disruptions and risks associated with the release process.
