An operational-level agreement (OLA) defines interdependent relationships in support of a service-level agreement (SLA). [1] The agreement describes the responsibilities of each internal support group toward other support groups, including the process and timeframe for delivery of their services.
Multilevel SLA: The SLA is split into the different levels, each addressing different set of customers for the same services, in the same SLA. Corporate-level SLA: Covering all the generic service level management (often abbreviated as SLM) issues appropriate to every customer throughout the organization. These issues are likely to be less ...
The SLA is the entire agreement that specifies what service is to be provided, how it is supported, times, locations, costs, performance, and responsibilities of the parties involved. SLOs are specific measurable characteristics of the SLA such as availability, throughput, frequency, response time, or quality.
When the expense of mechanisms to provide QoS is justified, network customers and providers can enter into a contractual agreement termed a service-level agreement (SLA) which specifies guarantees for the ability of a connection to give guaranteed performance in terms of throughput or latency based on mutually agreed measures.
'Normal service operation' is defined here as service operation within service-level agreement (SLA). It is one process area within the broader ITIL and ISO 20000 environment. ISO 20000 defines the objective of Incident management (part 1, 8.2) as: To restore agreed service to the business as soon as possible or to respond to service requests. [14]
A call's SLA can be generated from its metadata, such as the customer, department, site, inventory item, or problem profile associated with the call. Each SLA incorporates a "response time" and "fix time" related to the call. Triggers are programmed based on the response time and fix time to ensure the SLA is not violated. For instance, if a ...
The term "Service Level Agreement" (SLA) is frequently used for all aspects of a service level, but in more precise use one may distinguish: [4] Service Level Indicator (SLI): measures of service level, like availability (uptime); Service Level Objective (SLO): objectives based on these indicators, like 99.95% availability;
SLIs form the basis of service level objectives (SLOs), which in turn form the basis of service level agreements (SLAs); [1] an SLI can be called an SLA metric (also customer service metric, or simply service metric). Though every system is different in the services provided, often common SLIs are used.
