 Understanding KPIs:

Key Performance Indicators (KPIs) are metrics used to evaluate the efficiency and effectiveness of a process. They must be accurate and relevant to provide meaningful insights.

 Process Inefficiency Despite No Control Issues:

If a KPI shows inefficiency but no control issues are noted, it suggests that the KPI may not be accurately reflecting the process performance.

Recalibrating the KPI ensures that it correctly measures what it is intended to, providing a true picture of the process efficiency.

 Steps for Recalibration:

Review the current KPI and its alignment with process objectives.

Adjust the KPI parameters or thresholds to better reflect process performance.

Validate the recalibrated KPI with historical data to ensure accuracy.

 Comparing Other Actions:

Implementing New Controls:Premature without understanding the root cause of the KPI discrepancy.

Redesigning the Process:Extensive and unnecessary if the KPI is simply miscalibrated.

Re-Evaluating Existing Control Design:Important but secondary to ensuring KPI accuracy.

 References:

The CRISC Review Manual emphasizes the importance of accurate KPIs in monitoring process performance and the need for recalibration when discrepancies are found (CRISC Review Manual, Chapter 3: Risk Response and Mitigation, Section 3.14 Key Performance Indicators)​​.

Obfuscating customer information ensures data privacy by rendering sensitive details unintelligible to unauthorized parties, reducing the risk of exposure during transit or processing. This aligns withData Protection and Privacy Regulationsunder risk management frameworks, emphasizing safeguarding personally identifiable information.

Mean time between failures (MTBF) is a key performance indicator (KPI) that measures the average time that a system or component operates without interruption or failure. MTBF is a common metric for reliability and availability of IT services. A higher MTBF indicates a lower frequency of failures and a higher ability to deliver uninterrupted IT services. According to the CRISC Review Manual 2022, MTBF is one of the KPIs for IT service delivery1. According to the CRISC Review Questions, Answers & Explanations Manual 2022, MTBF is the correct answer to this question2.

Mean time to recover (MTTR), planned downtime, and unplanned downtime are not the best KPIs to measure the ability to deliver uninterrupted IT services. MTTR measures the average time that it takes to restore a system or component to normal operation after a failure. Planned downtime measures the scheduled time that a system or component is not available for use due to maintenance or upgrades. Unplanned downtime measures the unscheduled time that a system or component is not available for use due to failures or incidents. These KPIs are useful for measuring the impact and duration of service interruptions, but they do not directly reflect the ability to prevent or avoid service interruptions.
