Match each business continuity and resiliency metric on the left with its corresponding operational impact definition on the right.
- Recovery Point Objective (RPO)The maximum acceptable amount of data loss, measured in time, that an organization can tolerate following a disruption.
- Recovery Time Objective (RTO)The maximum targeted duration of system downtime permitted between an outage and service restoration.
- Mean Time to Repair (MTTR)The average time required to troubleshoot, repair, and restore a failed system component to active service.
- Mean Time Between Failures (MTBF)The statistical metric representing the expected operational uptime of a repairable component between hardware breakdowns.
Cevap
Recovery Point Objective (RPO) matches maximum acceptable data loss; Recovery Time Objective (RTO) matches maximum targeted service restoration time; Mean Time to Repair (MTTR) matches average repair/restoration time; Mean Time Between Failures (MTBF) matches expected operational uptime between failures.
Each continuity metric precisely addresses a different aspect of risk assessment and system availability: RPO establishes data backup requirements, RTO establishes recovery speed goals, MTTR measures repair efficiency, and MTBF measures component reliability.

Core BIA metrics (RTO, RPO, MTTR, MTBF) define operational impact, backup thresholds, service availability goals, and hardware reliability requirements.
