Objective: ITIL Application Development aims to make available applications and systems which provide the required functionality for IT services. This ITIL process includes the development and maintenance of custom applications as well as the customization of products from software vendors.

Part of: Service Transition

Process Owner: Application Developer

 

Process Description

Application Development is barely mentioned in the ITIL books, as ITIL focuses on different topics like service design and rollout. At IT Process Maps we decided to bridge that gap by introducing an Application Management process which takes care of application coding and the customization of software packages.

Even if ITIL Application Management is generally regarded a field of its own, we think an Application Management process should be included in any ITIL process structure to make sure there are clearly defined interfaces between the design, development and rollout stages of a service. The process overview of ITIL Application Development (.JPG) shows the key information flows (see Fig. 1).

Note: ITIL 2011 does not provide a detailed explanation of all aspects of Application Development. Rather, it highlights the key activities and assists in identifying the interfaces with other Service Management processes.
