Final answer:
A Service Level Agreement (SLA) is a document that outlines the support services one organization will provide to another, detailing service expectations and compensation arrangements for the supplier.
Step-by-step explanation:
The document that defines the support one organization provides to another and outlines how the supplier will be compensated or reimbursed is commonly referred to as a service level agreement (SLA). A SLA is a contractual agreement where the services to be provided are defined, as well as the level of service expected from the supplier. It also covers the metrics by which services are measured, duties and responsibilities of both parties, and the compensation for the supplier, which could be in the form of payment or other terms agreed upon.
SLAs are often used in the context of IT services, outsourcing, and telecommunications to ensure that the supplier provides the agreed-upon level of service and to protect both the supplier and the client in their business transaction. The agreement helps to set clear expectations and provides a framework for understanding the scope and quality of service to be rendered, along with any potential penalties for service level breaches.
