Difficulty: EasyBusiness Impact Analysis and Business Continuity Management

Match each Business Impact Analysis (BIA) and business continuity metric on the left to its corresponding operational definition on the right.

  • Recovery Time Objective (RTO)The targeted maximum duration of system downtime permitted following a disruption.
  • Recovery Point Objective (RPO)The maximum acceptable time period of data loss measured back from an outage.
  • Mean Time Between Failures (MTBF)The statistical average time a component or system operates continuously before breaking down.
  • Mean Time to Repair (MTTR)The average time required to diagnose, fix, and restore a non-functional component to service.

Answer

Recovery Time Objective matches the targeted maximum duration of system downtime. Recovery Point Objective matches the maximum acceptable time period of data loss. Mean Time Between Failures matches the statistical average operational time before breaking down. Mean Time to Repair matches the average time required to diagnose, fix, and restore a component.
Each business continuity term is accurately paired with its primary metric definition: Recovery Time Objective defines maximum allowed service disruption time; Recovery Point Objective defines allowable data loss age; Mean Time Between Failures measures operational lifespan between breakdowns; and Mean Time to Repair measures mean resolution duration.

Step-by-Step Solution

1
Differentiate downtime metrics from data loss metrics.
Recovery Time Objective (RTO) governs acceptable downtime duration, whereas Recovery Point Objective (RPO) governs tolerable data loss back-time.
RTO focuses on service restoration timing, while RPO determines necessary backup frequency to limit lost transactions.
2
Differentiate failure frequency metrics from service restoration metrics.
Mean Time Between Failures (MTBF) measures continuous uptime reliability, whereas Mean Time to Repair (MTTR) measures mean duration of maintenance.
MTBF quantifies how often failures occur over time, while MTTR quantifies how quickly repairs are completed.
