IT Service Management (ITSM) refers to the process by which IT teams administer the end-to-end service delivery to clients. This encompasses all processes and activities involved in the design, development, delivery, and support of information technology services.
An SLA is a contractual agreement between a customer and a supplier that defines the service level the supplier must achieve. It extends the service definition from the Service Catalogue by providing a series of service-level targets and performance metrics that specify the desired results. Here's an example of an incident resolution goal: 90 percent of priority incidents must be resolved within four hours.
CMDB baselines help to understand and control the changes that have been made to a configuration item(CI) after its Baseline has been created. The baseline is the snapshot of a CI.
An ACL is an Access Control List that defines what data a user can access and how they can access it in service now.
