Customized IT application

Applicability

The customized IT application scenario supports the execution of those projects where an IT application is developed for the specific needs of one or more specialist areas (user needs) and is integrated both technically and organizationally.

Phases and milestones

The customized IT application scenario comprises the phases and milestones shown in Figure 13:

Figure 13: Phases and milestones of the customized IT application scenario
Figure 13: Phases and milestones of the customized IT application scenario

The milestones are assigned to the hierarchy levels of steering, management and execution.

Call for tender and award decisions made within the framework of procurement depend on the requirements of the project and the project's progression, and are basically possible whatever the phase, assuming necessary outcomes (project foundations).

Modules

The customized IT application scenario consists of the modules shown in Figure 14:

The scenario can be further adapted to the specific project. For example, if it is not necessary to replace a legacy system, the IT migration module can simply be removed.
