The objective of the OLA is to present a clear, concise and measurable description of the service provider's internal support relationships. OLA is sometimes expanded to other phrases but they all have the same meaning: organizational-level agreement; operating-level agreement; operations-level agreement.

The output received by the customer as a result of the service provided is the main focus of the service level agreement. Service level agreements are also defined at different levels: Customer-based SLA: An agreement with an individual customer group, covering all the services they use. For example, an SLA between a supplier (IT service ...
The SLA is the entire agreement that specifies what service is to be provided, how it is supported, times, locations, costs, performance, and responsibilities of the parties involved.

Besides the input of the SLA, the Plan sub-process also works with the policy statements of the service provider itself. As said earlier these policy statements are defined in the control sub-process.

Though every system is different in the services provided, often common SLIs are used.
