Application management usually consists of five phases, performed by the service provider and in cooperation with the customer. First of all, the current status is analyzed. Based on this status, common goals can be defined, which should be achievable through management. Now, on this basis, the applications must be selected with which these goals can be achieved within an application environment that is as simple as possible. Once this has been done, the applications can be implemented in the company. Here, the manager is responsible for monitoring them during operation and watching out for problems. The applications must be monitored and maintained during the process. Proactive activity is therefore required here, as maintenance work should be carried out before problems arise. The expansion and optimization of the applications on the various systems is the final task in managing the applications. In this way, it can be ensured that the companies and their applications remain up to the daily challenges.
