Create a UI design (wireframe).
In the concept phase, the usage requirements are transferred into a prototype of the application. The focus is on the basic structure of the application and its pages. It is important to remain abstract, i.e. not to get lost in visual details. In this phase, it is not (yet) the appearance of the application that is crucial, but the "how".
The result of this phase is a visual representation of the application based on the user's requirements. The range of the visual representation ranges from simple sketches (paper-prototype) to detailed, interactive high-fidelity prototypes which already have great similarity to the real system.
# Questions to be answered in this phase
- How does the application work?
- How is the application structured?
- How can the user perform his task(s) with the application as efficiently, effectively and satisfactorily as possible?
