Which of the following metrics would you most associate with the Service Desk?

The primary function of a Service Desk is to act as the single point of contact for users to report service disruptions. This process is known as Incident Management. A key performance indicator (KPI) for the Service Desk is tracking the volume and severity of these disruptions. The number of high-priority incidents is a critical metric used for resource allocation, escalation, and reporting on the immediate health of IT services. It directly measures the immediate workload and impact handled by the Service Desk.

B. The support team which resolves the greatest number of problems: This is a metric for Problem Management, a separate process focused on root cause analysis, not the front-line Service Desk function.
C. The number of problems solved in a day: This metric also relates to Problem Management. The Service Desk's focus is on restoring service (resolving incidents), not necessarily identifying and solving underlying problems.
D. The mean time between failure: This is a reliability metric used in Availability or Capacity Management to measure the uptime of a component or service, not a direct operational metric for the Service Desk.

1. University Courseware: University of Wisconsin-Madison, IT Service Management. "Incident Management Key Performance Indicators (KPIs)." The document lists "Number of Incidents (by priority, category, etc.)" as a fundamental KPI for the Incident Management process, which is owned and executed by the Service Desk. (Available through DoIT, University of Wisconsin-Madison's public documentation on ITSM).

2. Academic Publication: Marrone, M., & Kolbe, L. M. (2011). "Uncovering ITIL claims: IT executives’ perception on benefits and performance." Journal of Strategic Information Systems, 20(3), 300-312. This article discusses ITIL processes and their perceived benefits. It implicitly supports the distinction that the Service Desk handles incidents (Table 2, p. 304), while Problem Management focuses on root causes, making incident-based metrics (like volume by priority) central to the Service Desk.

3. Academic Publication: Idrees, N., & Xu, L. (2012). "A Framework for Measuring the Performance of IT Service Management." Proceedings of the World Congress on Engineering 2012 Vol II. This paper outlines various metrics for ITSM processes. In Section IV, Table I, under "Incident Management," it lists "Number of incidents per period" and "Number of incidents per priority" as key metrics, reinforcing that these are central to the function most associated with the Service Desk.
