What BEST describes the value of service transition to the business?

Creating and maintaining a service catalogue is an output of Service Design through the Service Catalogue Management process, not Service Transition.

Service Transition manages the movement of new or changed services into the live environment using repeatable, disciplined processes, which builds quality and reliability incrementally across each release. This systematic approach reduces risk, increases stakeholder confidence, and yields measurable improvement in service quality with each successive transition. The cumulative effect is a continual upward trend in delivery quality.

Quick and effective access to standard services describes the value provided by Service Operation through the Request Fulfillment process.

Higher volumes of successful change is a measurable metric outcome of Service Transition but does not fully capture the broader business value of continual quality improvement it enables.
