4. Section 4: Disaster Recovery Failover Execution & Failback Recovery Verification

This section evaluates the effectiveness of disaster recovery mechanisms, failover execution fidelity, and recovery verification processes. Performance against RTO/RPO targets determines architectural resilience adequacy.


Was the formal Disaster Recovery (DR) Plan activated during this incident?


Was a failover to secondary region or backup system attempted?


Did the failover execution succeed within the defined Recovery Time Objective (RTO)?


Was data integrity maintained within the Recovery Point Objective (RPO) tolerance?


Was a failback to primary environment successfully executed?


Were any DR automation scripts or Infrastructure as Code (IaC) playbooks executed?


Rate the overall effectiveness of the DR plan execution (1-5 stars)

How recently was the DR plan tested prior to this incident?

Key lessons learned about DR architecture and failover mechanisms

5. Section 5: Enterprise Chief Information Officer (CIO) & Risk Management Director Sign-Off

This final section ensures executive accountability, risk register updates, and formal approval of corrective action plans. Leadership sign-off mandates resource allocation and strategic risk treatment decisions.
