A municipal public safety agency is establishing continuity metrics for its computer-aided dispatch (CAD) emergency response system following a Business Impact Analysis (BIA). Match each business continuity metric on the left with its corresponding operational definition on the right.
- Recovery Time Objective (RTO)The target duration of time within which infrastructure and CAD application services must be restored after an outage.
- Recovery Point Objective (RPO)The maximum acceptable period of transactional data loss measured in time, determining data backup frequency.
- Mean Time Between Failures (MTBF)The statistical indicator of component reliability representing the average expected uptime between system outages.
- Maximum Tolerable Downtime (MTD)The absolute total threshold of operational interruption permissible before irreversible organizational damage occurs.
Answer
Recovery Time Objective (RTO) matches the target duration for service restoration; Recovery Point Objective (RPO) matches the maximum acceptable period of data loss; Mean Time Between Failures (MTBF) matches the statistical indicator of system reliability; and Maximum Tolerable Downtime (MTD) matches the total permissible threshold of outage duration.
Each business continuity term directly corresponds to its core BIA metric definition: RTO sets the target timeframe for system restoration, RPO sets the maximum acceptable window of lost data, MTBF calculates hardware/system reliability over time, and MTD sets the maximum overall outage threshold an organization can sustain.
