Service level agreements can contain many service performance metrics with appropriate service level objectives. A common case in IT service management is a call center or services. Service level agreements are also defined at different levels: if a contractor agrees to provide a service for remuneration, a service contract defines the terms of that agreement. Service contracts can also be used by a manufacturer to define the terms of an extended warranty and explain the coverage or cost of services provided for a product if it does not work for a given period of time. It is important to keep in mind that the most important aspect of any service contract is the description of the services provided. If you write this part of the contract, you should be as specific as possible to ensure that there is no room for misunderstandings between you and the client. If your company still offers the same services to every customer, you may want to spend a lot of time defining the services provided in your boiler platform. Otherwise, every time you create a contract, take the time to make sure that the client`s specific goals and expectations are detailed in the contract. If you offer creative services such as writing or graphic design, you should also indicate how many revisions are included, or you can work indefinitely for someone who will never be 100% convinced that what they had imagined in their head will not be able to materialize. A Web Service Level Agreement (WSLA) is a standard for monitoring compliance with Service Level Agreements for Web services.
Authors can specify the performance assigned to a web service application, the desired performance goals, and the actions to take if performance is not achieved. Since the late 1980s, SLAs have been used by fixed telecommunications operators. Today, SLAs are so prevalent that large organizations have many different SLAs in the company itself. Two different units in an organization write an SLA, one being the customer and the other the service provider. This approach helps maintain the same quality of service across different units of the organization and across multiple locations in the organization. This internal SLA scripting also makes it possible to compare the quality of service between an internal department and an external service provider.  As a general rule, a service contract should include a description of the services provided and their frequency, identification of the parties, the timing or frequency of monitoring or surveillance services (if necessary), the rates for the services provided, how and when payments are to be made, when and how a contract can be terminated, how to resolve disputes related to the contract and, if applicable, Contingency Plan. Some contracts also contain provisions relating to confidentiality or protected information. Many SLAs meet the specifications of the Information Technology Infrastructure Library when applied to IT services.
