A fundamental component of a service catalog is a Service Level Agreement (SLA). SLAs define the expectations and requirements of service delivery between an organization and its customers. SLAs outline the services provided, response time, quality of service, cost, and other important details. SLAs are essential for ensuring that both parties understand the agreement and can hold each other accountable. Additionally, SLAs help ensure that customers receive the quality of service they expect and that organizations can efficiently deliver the services they promise.
