    • Review: All key links and roles in the recovery process root cause locating, decision-making, handling, contingency plan execution, rollback, and clearance.
    • Analysis: Root causes for faults and the potential for improvement in fault handling are analyzed.
    • Summary: The fault and the recovery process are summarized, including the fault nature, responsibility evaluation, and experience and lessons learned.
    • Action: Based on the summary, improvement measures are proposed and taken.
