Set a good base number. Defining the right measures is only half the fight. To be useful, measures must be set at reasonable and achievable performance levels. In the absence of solid historical measurement data, you should be prepared to review and adjust parameters later through a predefined process specified in ALS. The SLA metrics required depend on the services provided. Many elements can be monitored as part of an ALS, but the scheme should be kept as simple as possible to avoid confusion and excessive costs on both sides. When selecting metrics, check the process and decide what is most important. The more complex the monitoring scheme (and associated corrective measures) is, the less likely it is to be effective because no one will have time to properly analyze the data. If in doubt, opt for the simple collection of metrics; Automated systems are the best, as expensive manual metric input is unlikely to be reliable. Services – Power measurements and power levels are defined. The customer and service provider should agree on a list of all the metrics they use to measure the service levels of the provider. Most service providers have standard SLAs – sometimes several, which reflect different levels of service at different prices – which can be a good starting point for negotiations. However, these should be audited and modified by the client and the lawyer, as they are generally favourable to the supplier.
Are you actively monitoring your WAN service level agreement? Measures should be designed so that bad conduct is not rewarded by both parties. If z.B. a service level is violated because the customer does not provide information on time, the provider should not be penalized. Ideally, ALS should be aligned with the technological or commercial objectives of the commitment. The wrong direction can have a negative impact on the pricing of deals, the quality of the service delivery and the customer experience.
