In this step, we take the sketch and interview script and start building the high-fidelity, real-looking screens. We want to build a prototype that is as realistic as possible so that users provide us with as much feedback as possible.
Now, we stitch all the screens together and add real data and animations. We build a prototype that looks and feels like an actual product.
Before conducting the actual user study, we complete a dry run. The interviewer does a mock test with a team member using the interview script and the prototype.
We have a final opportunity to tweak and improve any glitches discovered during the dry run.
