The remediation plan should be evaluated at what point in the change lifecycle?

Evaluating the remediation plan before approval is a required step in the change assessment process, ensuring a tested backout strategy is agreed upon before any work begins. This prevents teams from scrambling to define a rollback procedure during an active failure scenario. Pre-approval evaluation also allows the change advisory board to reject changes that lack an adequate remediation plan.

Evaluating the remediation plan only after the change has already failed is too late, as a backout procedure must be pre-approved and ready before implementation begins.

Assessing the remediation plan after implementation means there is no pre-approved recovery path during the change window, which defeats the plan's purpose.

Waiting until after a post-implementation review to evaluate the remediation plan leaves the change without an approved rollback strategy throughout the entire implementation phase.
