Performance and Control Audit and maintenance of the accounting system to provide consolidated reports for existing non-recurring projects and service lines are required to monitor financial performance on a monthly basis. These include the monthly year, the previous year and the actual annual activity in relation to the budget, as well as the declaration of the life cycle of the contract. Significant discrepancies are being studied, both within and at the third level, to take action. 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.  Many SLAs follow the specifications of the IT infrastructure library when applied to IT services. 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. The service received by the customer as a result of the service provided is at the heart of the service level agreement. Any member applying for membership under this agreement must respect their original reputation. These include the payment of annual salaries and the annual coverage of the CPD. Service level agreements are also defined at different levels: all applicants with a university degree must have at least 3 years of professional experience with at least 24 months of professional qualification. The main point is to create a new level for the grid, cloud or SOA middleware, capable of creating a trading mechanism between service providers and consumers. For example, the EU-funded Framework SLA@SOI 7 research projectexplores aspects of multi-level, multi-supplier slas within service-based infrastructure and cloud computing, while another EU-funded project, VISION Cloud, has delivered results in terms of content-based ALS.
A Service Level Contract (SLA) is an obligation between a service provider and a customer. Specific aspects of the service – quality, availability, responsibilities – are agreed between the service provider and the service user.  The most common component of ALS is that services are provided to the client in accordance with the contract. For example, internet service providers and telecommunications companies will generally include service level agreements under the terms of their contracts with customers to define service levels of service level sold in plain language. In this case, ALS generally has a medium-time technical definition between errors (MTBF), average repair time or average recovery time (MTTR); Identifying the party responsible for reporting errors or paying royalties; Responsibility for different data rates throughput; Jitter; or similar measurable details.
