Question

Difficulty: MediumBusiness Impact Analysis and Business Continuity Management

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.

Step-by-Step Solution

1
Differentiate between time-to-restore metrics and data-loss tolerance metrics.
Identify RTO as system restoration target time and RPO as data age/loss limit.
RTO focuses on downtime duration, while RPO focuses on database transaction recovery.
2
Analyze reliability metrics versus absolute interruption caps.
Map MTBF to operational equipment reliability and MTD to the maximum operational outage boundary.
MTBF estimates frequency between failures, while MTD caps overall outage allowance before catastrophic impact.
