Certified in Risk and Information Systems Control (CRISC) — Question 105

Which of the following is the BEST key performance indicator (KPI) to measure the ability to deliver uninterrupted IT services?

Answer options

• A. Mean time between failures
• B. Unplanned downtime
• C. Mean time to recover
• D. Planned downtime

Correct answer: B

Explanation

Unplanned downtime is the best KPI for measuring the ability to deliver uninterrupted IT services because it directly reflects unexpected service interruptions. In contrast, mean time between failures and mean time to recover focus on the frequency and recovery from failures, while planned downtime does not indicate service delivery performance during unplanned events.
