The Four Phases of Release & Deployment
Release and deployment planning - During this phase, plans for creating and deploying the release are created. It starts with a change management authorization to plan a release and ends with change management authorization to create the release. This may be separate authorizations, or it may be a single authorization to proceed with all activity. The number of authorizations and the amount of change management involvement is based upon the risk associated with this particular release.
Release build and test The release package is built, tested and checked into the DML. This phase starts with change management authorization to build the release and ends with change management authorization for the baselined release package to be checked into the DML by service asset and configuration management. This phase only happens once for each release.
Deployment The release package from the DML is deployed to the live environment. This phase starts with change management authorization to deploy the release package to one or more target environments and ends with handover to the service operation functions and the provision of early life support. There may be one, or many separate deployment phases for each release, depending on the planned deployment options.
Review Activities and close Experience and feedback are captured, performance targets and achievements are Review Activitiesed and lessons are learned and documented. Modifications to the release and deployment process will be considered.
