Procedure and method
We analyzed the existing customer portal with a focus on layout, user guidance, comprehensibility and usefulness from the user's point of view and identified potential for improvement. In several sprints we built the new UX concept and deliberately made sure to reuse the elements and processes that worked. The Axure prototype - the clickable concept - was always accessible to project managers and developers, which allowed for short iteration cycles. At the same time, of course, the prototype served as a great basis for user testing.
The visual design was continuously integrated into the prototype. Users were also involved at a very early stage: The concept was validated in usability testing with end users before it was programmed by the developers. The functionalities were and still are extended step by step.
