AlS presents mutual understanding between services, priorities, responsibilities, guarantees and guarantees. A « service level » must be identified for each service area. SLA can determine availability levels, performance and operation, or other service functions such as invoices. The level of service can also be defined as « target » and « minimum » that allows customers to inform about what they expect (minimum), while the measured target value (average) indicating the organization`s level of performance is expanded. In some contracts, penalties may be accepted for the absence of ALA (see « Customer Affairs » below). It is important to note that the « agreement » is about the services the customer receives and not about how the service provider provides them. The concept of service agreements has been expanded and applied in a number of institutions as an effective method of measuring and operating internal services and as a cost redistribution mechanism, which gradually expanded the concept of service agreements within these institutions during the first decade of the century. The main feature of this extension is the development of service agreements comprising a large number of types of services considered financially indirect costs in these organizations, so that they can be monitored financially and administratively. These mechanisms have also been used to support restructuring mechanisms within institutions. From a business perspective, you may need to consider service level management if you need to differentiate between service (for example. B gold, silver and bronze or) and if you have a different price for each level of service. (Experts) Service providers can show value by organizing themselves creatively, skilledly and knowledgefully to provide the necessary service, perhaps in innovative ways.
