Typically, these processes and methods are left to the outsourcing company to determine that these processes and methods can support the ALS agreement. However, it is recommended that the client and the outsourcing company work together during the SLA contract negotiations to clear up misunderstandings about the support process and method, as well as management and reporting methods. For example, the sales manager can open applications by creating tickets that use standard ALS for the department, or a more restrictive ALS for business management or an ALS for a specific service within the department as “providers.” Define carefully. A supplier can optimize ALS definitions to ensure they are met. For example, the Incident Response Time measure is designed to ensure that the provider corrects an incident within a minimum of minutes. However, some providers can complete ALS 100% by providing an automated response to an incident report. Customers should clearly define ALS so that they represent the intent of the level of service. Since the late 1980s, SLAs have been used by fixed-line operators. Today, ALS is so widespread that large organizations have many different ALSs within the company itself. Two different units in an organization script an ALS, one unit being the customer and another the service provider.
This helps maintain the same quality of service between different units of the organization and in several sites within the organization. This internal ALS script also compares the quality of service between an internal service and an external service provider.  In addition to defining the services to be provided, the contract should also document how services should be controlled, including how data is collected and reported, how often it is verified, and who is involved in the audit. On the other hand, if we also have a stand where we offer juices throughout the day, but at fixed prices and where B and C customers can buy their needs, this is a service-based ALS. This graph illustrates the service agreement management process and its activities, as well as the state model that is reflected in the development of the service dataset. The third and final type of service level agreement is multi-level ALS. In multi-level ALS, aspects of ALS are defined by the client`s organization with a kind of heredition with global definitions relevant to all lower levels. This ALS focuses on the client`s organization.
