Availability Management

             

              The class was introduced to Availability Management.

             

              The professor presented the Availability Management for IT services. He noted that in the ITIL training framework, availability is determined by three key aspects: Reliability, Maintainability, and Serviceability.

              It was discussed that Reliability is the measure of how long a service can perform without interruption. Maintainability is the measure of how quickly a failed service can be restored. Serviceability is the measure of how effectively third party suppliers deliver their services.

              The ITIL availability management process has a set step of activities in place to avoid system failure and to ensure that the service is available to the customer at the agreed standards. ITIL availability management is a process that is especially important during the Service Design stage of the ITIL service lifecycle and also in the Continual Service Improvement stage of the ITIL service lifecycle.

                   In my opinion, without ITIL availability management, services run the risk of failing more often than it should and that could cost revenue if the customers move their business elsewhere because the IT service provider produced unreliable services. This is why it’s important to agree upon standards for Reliability, Maintainability, and Serviceability. When these three aspects are measured against the standard and found to fall short of expectations, the problem can be addressed with contingency plans that were devised after risk assessment in the ITIL availability management process.
