What metric represents the average amount of time it would take to repair an asset or component after a disaster?

• A. Mission Essential Functions (MEFs)
• B. Mean Time to Repair (MTTR)
• C. Recovery Service Level (RSL)
• D. Privacy Impact Assessment (PIA)

Answer: (B)

The main idea is understanding how we measure downtime during recovery. The metric that captures the average time it would take to repair an asset or component after a disaster is Mean Time to Repair. MTTR reflects the typical duration from when a fault or failure is detected to when the asset is repaired and back in operation, including the steps of diagnosis, repair work, testing, and handover. This measure helps teams plan for outages, set realistic downtime expectations, and identify bottlenecks in the repair process so recovery efforts can be improved. Other terms describe different concepts: Mission Essential Functions focus on the critical operations that must continue rather than how long repairs take; Recovery Service Level defines the target time to restore services but isn't the actual repair duration; Privacy Impact Assessment evaluates privacy risks, not repair timing.
