Release Management: Backout phase

If the release fails to meet expectations or if serious problems are encountered during deployment, Problem Management may be required to help identify and diagnose the root cause of the problem. If a suitable fix or workaround can be found, it should be documented and a Request for Change (RFC) created to deploy the fix or workaround into the production environment. If no fix or workaround is found, it may be appropriate to use the backout procedures to remove the release from that environment. If the release needs to be backed out, this should also be recorded, including any information that supports this decision.

The Backout option is available during the Distribution and Rollout phase or the Verification phase.
