It is not uncommon for an internet service provider (or network service provider) to explicitly state its own ALS on its website.   The U.S. Telecommunications Act of 1996 does not specifically require companies to have ALS, but it does provide a framework for companies to do so in Sections 251 and 252.  Section 252 (c) (1) (”Duty to Negotiate”) obliges z.B. established local exchange operators (CIDs) to negotiate in good faith matters such as the sale of dentes` and access to whistleblowing channels. If services and technologies change, ALS may change to reflect improvements and/or changes. This ALS is checked every six months and updated if necessary. If updates are deemed necessary, the customer is asked to verify and approve the changes. If your service provider does not meet its obligations, this can have a significant impact on the reputation and end result of your organization. In your ALS, you should include the consequences if performance standards are not met. These fines can help your organization in the event of losses.
It also protects your organization and makes your supplier accountable. IT service organizations that manage multiple service providers may wish to enter into Operational Level Agreements (OLA) that explain how some parties involved in the IT service delivery process interact with each other to maintain performance. Tools to automate the collection and display of performance data at the service level are also available. 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.
 Outsourcing involves transferring responsibility from an organization to a supplier. This new agreement is managed by a contract that may include one or more SLAs. The contract may include financial penalties and the right to terminate if one of the SLAs metrics is routinely missed. The definition, monitoring and management of ALS is an important part of managing the outsourcing relationship (ORM) discipline. Specific SLAs are generally negotiated in advance as part of the outsourcing contract and are used as one of the main tools for outsourcing governance. Customers can create common metrics with multiple service providers that take into account the multi-supplier impact and impact the creditor may have on processes that are not considered to be in compliance with the contract.
