Application Management ITIL tasks are outlined in the Application Management book from OGC.
This considered they fall within the Application lifecycle which focuses on six key phases, outlined below.
Application Management ITIL tasks – Requirements This is the phase during which the requirements for a new application are gathered, based on the business needs of the organisation.
It is important to note that there are three types of requirements for any application – functional requirements, non-functional requirements, and usability requirements.
Application Management ITIL tasks – Design This is the phase during which requirements are translated into feature specifications.
The goal for application designs should be satisfying the organization’s requirements.
Design includes the design of the application itself, and the design of the environment, or operational model, that the application has to run on.
Application Management ITIL tasks – Build In the build phase, both the application and the operational model are made ready for deployment.
Application components are coded or acquired, integrated, and tested.
Often the distinction is made between a development and test environment.
The test environment allows for testing the combination of application and operational model.
Application Management ITIL tasks – Deploy In this phase, both the operational model and the application are deployed.
The operational model is incorporated in the existing IT environment and the application is installed on top of the operational model, using the deployment processes described within ITIL ICT Infrastructure Management.
Application Management ITIL tasks – Operate In the operate phase, the IT services organisation delivers the service required by the business.
The performance of the service is measured continually against the Service Levels and key business drivers.
Application Management ITIL tasks – Optimize In the optimize phase, the results of the Service Level performance measurements are analyzed and acted upon.
Possible improvements are discussed and developments initiated if necessary.
The two main strategies in this phase are to maintain and/or improve the Service Levels and to lower cost.
This could lead to another iteration in the lifecycle or to justified retirement of an application.
