ITIL4F Key Concepts of IT Service Management Practice Question
An organization wants to improve its service desk performance. Which metric would best indicate that the service desk is effectively restoring service?
⚠ Common exam trap
PeopleCert often tests the distinction between efficiency metrics (like FCR or tickets closed) and effectiveness metrics (like MTRS), trapping candidates who confuse 'restoring service' with 'resolving on first contact' or 'closing tickets quickly.'

Correct answer & explanation
✓
Mean Time to Restore Service (MTRS)
Mean Time to Restore Service (MTRS) directly measures the average time taken to fully restore a service after a failure, making it the best metric for assessing how effectively the service desk restores service. ITIL 4 defines MTRS as the elapsed time from when a service fails to when it is fully restored, including diagnosis, repair, and verification. A lower MTRS indicates faster restoration, which is the core objective of incident management.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Customer satisfaction score
Why it's wrong here
While customer satisfaction is a crucial outcome for any service organization, it serves as a lagging indicator influenced by numerous factors beyond just the speed of service restoration, such as communication quality, professionalism, and perceived value. It does not directly provide actionable insights into the operational efficiency or speed of the restoration process itself. Therefore, it's not the most direct metric for pinpointing areas to improve the technical performance of service restoration.
- ✓
Mean Time to Restore Service (MTRS)
Why this is correct
Mean Time to Restore Service (MTRS) is a critical operational metric that precisely quantifies the average duration from the detection of a service failure or incident until the service is fully operational again. For an organization focused on enhancing its service desk performance, particularly in minimizing service disruption, MTRS provides a direct and measurable target. Reducing MTRS directly reflects improvements in incident management processes, diagnostic capabilities, and the overall effectiveness of the service desk in rapidly restoring business-critical services.
- ✗
Number of tickets closed per agent
Why it's wrong here
The number of tickets closed per agent is primarily a productivity metric, reflecting an individual's workload capacity and output volume. While it indicates how busy an agent is, it does not inherently measure the quality, complexity, or, crucially, the speed and effectiveness of service restoration for critical incidents. Focusing solely on this metric could incentivize closing simple tickets quickly, potentially overlooking the timely resolution of more impactful service outages.
- ✗
First Call Resolution (FCR) rate
Why it's wrong here
First Call Resolution (FCR) rate measures the percentage of incidents or service requests resolved during the initial contact with the service desk, significantly contributing to customer satisfaction and efficiency. However, FCR specifically focuses on immediate resolution at the first point of contact, not the overall average time taken to restore *all* services, especially those requiring escalation or deeper investigation. Therefore, while valuable, it doesn't directly capture the end-to-end speed of service restoration across the entire incident lifecycle.
