The term availability specifically refers to the performance of a service when it is needed, indicating how accessible or operational the service is at any given time. In the context of ITIL, availability ensures that users can access the service and fulfill their requirements without interruptions. This is crucial for maintaining service levels and ensuring that business operations can continue smoothly without significant downtime.

Understanding availability also involves recognizing the importance of meeting user demands and expectations whenever the service is called upon. While other concepts related to capacity, reliability, and support are valuable in assessing overall service quality, they do not capture the direct relationship that availability holds with users' immediate needs for performance at that specific time.
