This paper reports on our experience in using the MuiCSer process framework for the redesign of the user interface for operating an industrial digital printing system. MuiCSer is created to support the user-centered interface design of new and legacy systems by a multi-disciplinary team. The process framework is created to enhance increased flexibility, usability and sustainability of the designed user interfaces. Resulting user interfaces are decoupled from the application logic, but still help to maintain consistency with the available functionality even when this changes over time. This report focuses on the usage of the task model during the analysis of the current user interface, the creation of user interface prototypes at various fidelity levels and the still ongoing realization of a flexible user interface management system to support future changes of the deployed user interfaces.
