Can service operation improve efficiency in the business operation by automating common routines?

This is incorrect because automation directly reduces resource consumption and processing time, which is a measure of efficiency, not only effectiveness.

Service operation improves efficiency by automating repetitive tasks such as event monitoring and request fulfillment, reducing manual workload and error rates. Additionally, the Service Knowledge Management System (SKMS) provides staff with documented solutions and known-error records, enabling faster and more consistent resolution of incidents and requests. Together, automation and the SKMS allow more productive work to be completed with the same or fewer resources, directly improving operational efficiency.

While partially true, this answer is incomplete because it omits the contribution of the Service Knowledge Management System, which is a key ITIL mechanism for improving efficiency in service operation.

This is incorrect because automation does more than prevent problems - it also reduces time and resource costs on routine tasks, which directly improves operational efficiency.
