Which of the following is NOT a common metric for Service Request Management?

Incident Resolution Time is not typically considered a common metric for Service Request Management. Service Request Management focuses on the processes and metrics specifically related to handling service requests—often involving requests for information, access, or changes, rather than incidents, which are typically disruptions or changes in service that affect regular operations.

Common metrics for Service Request Management usually include Service Level Agreements (SLA), which define the expected service levels and performance commitments. Additionally, the volume of service requests processed and customer satisfaction are vital metrics that help assess the effectiveness and efficiency of the service request handling process.

In contrast, Incident Resolution Time pertains more to Incident Management, which is about restoring service after an interruption. Therefore, while Incident Resolution Time is an essential metric within the broader context of IT service management, it does not align with the core focus of Service Request Management.
