In a short time, we then develop a first prototype to make the favored ideas more tangible. We start with so-called low fidelity mockups. Participants are provided with pens, paper and sticky notes for an initial rough visualization of the ideas. The mockups serve our UI developers as a basis for a first prototype, so that the workshop participants can see their ideas on a mobile device or desktop and check their suitability a short time later. Often, changes are still made to the prototype. And that's absolutely fine, because that's the only way to find the best solution.
