Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  Percentage of SLAs met

  Why it's wrong here

  The 'Percentage of SLAs met' is a high-level metric primarily used in Service Level Management to assess the overall performance of a service provider against agreed-upon service targets. While it indicates the general quality and compliance of service delivery, often encompassing availability and capacity, it does not specifically measure the speed or efficiency of restoring service after an incident has occurred. It's a measure of ongoing service compliance, not the effectiveness of incident resolution processes.

• ✗

  Number of known errors

  Why it's wrong here

  The 'Number of known errors' is a key metric for Problem Management, quantifying the count of identified underlying causes of incidents that have been documented and are awaiting resolution or workaround. This metric reflects the backlog of systemic issues that could lead to future incidents. While reducing known errors can proactively prevent service disruptions, it does not directly measure the effectiveness or speed of restoring service once an incident has already occurred and is actively impacting users.

• ✓

  Mean Time to Restore Service (MTTR)

  Why this is correct

  Mean Time to Restore Service (MTTR) is the most appropriate metric for measuring the effectiveness of service restoration. It quantifies the average time taken from the start of an incident to the full restoration of the affected service to its normal operational state. MTTR directly reflects the efficiency of the incident management process, encompassing detection, diagnosis, repair, and verification, thereby providing a clear indicator of how quickly an organization can recover from service disruptions.

• ✗

  First Call Resolution (FCR) rate

  Why it's wrong here

  The 'First Call Resolution (FCR) rate' is a metric primarily focused on Service Desk performance, measuring the percentage of incidents or service requests that are fully resolved by the Service Desk during the initial contact with the user. While FCR indicates Service Desk efficiency and can improve customer satisfaction, it typically applies to simpler issues resolved at the first point of contact. It does not encompass the broader, often more complex, process of restoring service for incidents that require deeper technical intervention beyond the Service Desk's immediate capabilities.
