After successful training of users to use the deployed service, the release goes for the review. In the Review stage, the release reviewer with a team assesses the release, including the entire release process efficiency, cost and time effectiveness, impact, intended and incidental outcomes, and more. The processes involved in each stage of the release will be thoroughly inspected. The Review Board also determines whether the release met the specified goals causing little or no disruption to the production environment.
Analyses made in the Review stage will be documented into a report in exhaustive detail, to help the release management team retrospect and act proactively in the future.
