The system is developed or parameterized to the point where it meets the solution requirements and is ready for integration.

Based on the solution requirements of the system concept and the solution architecture, the detailed specifications are created. The system is realized:

1. when a system is procured, the procured system is parameterized and system enhancements are developed;
2. if customized development is envisaged for the system, the system is developed;
3. the user manual is produced.

The developer tests the system during realization before the first delivery to the user and operator.

Tests after the first delivery are supported by the tests module. The documentation compiled so far, in particular the system concept and the solution architecture, is updated as necessary and the user manual is produced.
