Service Description – ALS needs detailed descriptions of each service offered in all circumstances, including processing times. Service definitions should include how services are delivered, the provision of maintenance services, operating hours, dependencies, process structure and a list of all technologies and applications used. Service availability: The time available to use the service. This can be measured using the time window, z.B 99.5% availability between hours 8 a.m. and 6 p.m. and more or less availability at other times. E-commerce processes are generally extremely aggressive. 99.999 percent operating time is an unusual requirement for a website that generates millions of dollars per hour. These systems and processes are often controlled by specialized third-party companies. If this is the case, it is necessary that the third party is also involved in the AES negotiations. This will allow them to obtain details of the levels of service that should be monitored and explanations on how to prosecute them. A service level contract is an agreement between two or more parties, one being the customer and other service providers. It may be a formal or informal legally binding “treaty” (for example.
B internal relations within the department). The agreement may include separate organizations or different teams within an organization. Contracts between the service provider and other third parties are often referred to as SLAs (wrongly) – the level of service having been set by the (main) customer, there can be no “agreement” between third parties; these agreements are simply “contracts.” However, operational agreements or olea agreements can be used by internal groups to support ALS. If an aspect of a service has not been agreed with the customer, it is not an “ALS.” Service level agreements can contain many service performance metrics with corresponding service level targets. A common case in IT services management is a call center or service desk. Among the measures agreed in these cases are: this agreement aims to ensure the availability of the necessary elements and obligations to provide the service providers with consistent IT support and consistent provision by the service provider or providers.
