What metrics are commonly used in IT service management to measure performance?

• A. User satisfaction surveys alone determine service success.
• B. Availability, incident response time, resolution time, first-time fix rate, customer satisfaction, and SLA compliance.
• C. Number of new users per quarter as the sole metric.
• D. Hardware uptime is the only important metric.

Answer: (B)

In IT service management, you measure performance with a balanced set of metrics that cover how available and responsive the service is, how efficiently issues are handled, and how the service is perceived against agreed expectations.

The best answer combines availability, incident response time, resolution time, first-time fix rate, customer satisfaction, and SLA compliance. Availability shows the service is reachable when users need it. Incident response time reflects how quickly the team begins addressing problems after they’re detected. Resolution time measures how long it takes to completely fix issues. First-time fix rate indicates how often problems are resolved on the first attempt, signaling quality and efficiency. Customer satisfaction captures user experience and overall perception of the service, while SLA compliance verifies that the service is meeting agreed-upon performance targets. Together, these metrics provide a comprehensive view of both technical performance and user outcomes.

The other options don’t give a complete picture. Relying on user satisfaction alone ignores reliability and speed of service delivery. Focusing only on new user growth misses operational performance and user experience aspects. Looking at hardware uptime alone neglects service performance, incident handling, and user perception, which are central to IT service management.
