Event management, problem management, access management and request fulfillment are part of which stage of the service lifecycle?

Service Strategy focuses on defining the market, service portfolio management, and financial management - not the operational processes listed.

Service Transition covers change management, release and deployment, and service validation - it handles moving services into production, not managing them operationally.

Service Operation is the ITIL lifecycle stage responsible for the day-to-day management of live IT services. It encompasses key processes including event management, incident management, problem management, access management, and request fulfillment - all of which deal with ongoing operational activities rather than design, transition, or strategic concerns.

Continual Service Improvement focuses on measuring and improving service quality over time using metrics and improvement initiatives, not on running day-to-day operational processes.
