METRICS
Metrics should be put in place to measure the performance of the service desk. While call volumes are important to indicate required staffing levels, they are not a measure of service desk performance or something that the service desk can necessarily control.
Metrics include:
• the average time to resolve an incident (where the incident is resolved by the service desk and not subject to functional escalation);
• the percentage of calls resolved during the first call;
• the average time to escalate an incident (this can then be compared with the relevant SLA);
• the average cost of calls (calls will be different, but this figure is useful for planning and assessing long-term trends).
