✍️ Sample CSI Questions & Answers

1. How many times should each stage of the Plan, Do, Check, Act (PDCA) cycle be visited?

✓ The entire cycle should be repeated multiple times to implement Continual Improvement

Explanation: The correct answer states that the entire cycle of Plan, Do, Check, Act (PDCA) should be repeated multiple times to implement Continual Service Improvement. This means that after completing one cycle, the process should start again from the beginning, and this repetition helps in continuously improving the system or process. Each stage of the cycle is important and contributes to the overall improvement, and therefore, all stages should be visited multiple times for effective implementation of Continual Service Improvement.

2. In CSI, what does 'availability' as a metric typically measure?

✓ The percentage of agreed time that a service or component is functioning as required

Availability is expressed as a percentage of the agreed service hours during which the service is fully operational.

3. What does the 'R' in RACI stand for, and who typically holds it in a CSI data-gathering activity?

✓ Responsible; the person or team that performs the actual data collection

R stands for Responsible — the individual or team that does the actual work, in this case collecting and recording measurement data.

4. How many KPIs should typically be associated with a single CSF?

✓ A small number, usually two to five

Best practice recommends a small set of KPIs per CSF to keep measurement focused and actionable.

5. In CSI, why is it important that monitoring tools provide data at the right granularity?

✓ Too coarse a view hides problems; too granular a view creates data overload that obscures trends

Appropriate granularity ensures that monitoring data is detailed enough to reveal issues but not so voluminous that it overwhelms analysts.

6. What is the primary purpose of benchmarking in ITIL Continual Service Improvement?

✓ To compare current performance against an industry standard or best practice baseline

Benchmarking compares current performance against industry standards or best practices to identify gaps and drive improvement.
