Which service lifecycle stage provides the following values to the business?

Service Transition focuses on building, testing, and deploying service changes into the production environment rather than delivering ongoing operational value.

Service Strategy defines what services to offer and how to position the service provider competitively, operating at a planning level rather than delivering day-to-day value.

Service Operation delivers ongoing value to the business by performing the actual work of running services, including event management, incident management, request fulfillment, and access management. It is the stage where the strategic intentions and service designs are realized in practice, making it the primary source of direct, tangible value experienced by users and customers every day.

Service Design produces the blueprints and specifications for new or changed services but does not itself deliver the live operational value to the business.
