What is the main purpose of Service Operation in ITIL?

The main purpose of Service Operation in ITIL is to deliver the agreed levels of service to customers. This phase is crucial because it focuses on ensuring that the services provided are aligned with the needs and expectations of the users and stakeholders. Service Operation is responsible for day-to-day service management, addressing incidents, service requests, and fulfilling operational responsibilities efficiently and effectively.

Delivering agreed levels of service involves not only maintaining service availability and performance but also managing incidents and problems that arise during service delivery. It ensures that disruptions are minimized and that users can rely on IT services for their daily activities. This aligns with the broader goal of ITIL, which is to enhance customer satisfaction and ensure that IT services contribute positively to business objectives.

Other aspects, such as designing services or managing financial aspects, while important, fall under different stages of the ITIL lifecycle. They are more focused on planning and governance than on the operational delivery that Service Operation primarily addresses. Hence, focusing on delivering agreed levels of service is the primary function of the Service Operation phase within the ITIL framework.
