Which is an example of improving service utility using service management automation?

Pre-determined routing of a service request improves process efficiency and consistency, which relates more to service warranty (fitness for use) than to utility.

Reducing the time to compile service data is an operational efficiency gain for IT management, not an improvement to the service's fitness for purpose as experienced by users.

Monitoring service availability is a warranty-related activity - it ensures fitness for use by tracking uptime, not improving the functional utility of the service.

Utility is defined in ITIL as 'fitness for purpose' - the attributes of a service that positively affect the performance of tasks associated with desired outcomes. Faster resource allocation through automation directly increases the functional capability and responsiveness of a service, improving what it can do for the customer, which is the definition of improved utility.
