A Service Level Agreement (SLA) is a contract between a service provider and a client that specifies, in measurable terms, the services that the provider will furnish. Coursera's SLA catalogue teaches you the intricacies of developing, managing, and assessing SLAs. You'll learn about the vital components of an SLA such as service definitions, performance metrics, problem management processes, and the legal and financial implications of non-compliance. You'll also gain insight into how SLAs can be used as a tool for communication and managing expectations between a service provider and its clients. This knowledge is crucial for anyone involved in service delivery, project management, or client relations.
