Which one of the following is the BEST description of the purpose of the service operation stage of the service lifecycle?

Supplier engagement strategy is primarily a concern of service design and service strategy, not service operation.

Designing and building processes to meet business needs is the role of service design, not service operation.

The primary purpose of service operation is to deliver and manage IT services at agreed levels to business users and customers. It is responsible for the day-to-day running of services, ensuring value is actually realized by the business.
