What defines an IT service level agreement (SLA)?

• A. A contract defining expected service levels between a provider and client

It provides a framework for measuring the quality of service and offers protections for the client if the provider fails to meet the agreed standards.

Informal agreements among colleagues are often vague and not legally binding, lacking the structure and detail found in a formal SLA. Likewise, a guideline for service interruptions doesn’t capture the broader aspects of service levels and commitments defined within an SLA.
