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

Service Transition focuses on building, testing, and deploying new or changed services into production and does not itself deliver ongoing operational value.

Service Strategy defines the organizational direction and policies for service management but does not deliver services or realize value for day-to-day business operations.

Service Operation is the stage where day-to-day activities and processes for delivering and managing services at agreed levels are carried out, encompassing processes such as Incident Management, Problem Management, and Event Management. This is the stage where the utility and warranty of services are experienced by customers, meaning all the value designed and transitioned in earlier stages is actually realized here.

Service Design creates the blueprints and specifications for services and supporting processes but does not execute or deliver services to the business.
