We followed a pretty basic version of the Double Diamond design thinking process ; Discover (learn about the subject, the users, the problem), Define (make sure we are answering to the right problem, phrased the right way), Develop (ideate and imagine possible ways to answer these questions) and Deliver (prototype and test ideas). Given the time we hade and the scope of our mission within our client's project roadmap, we only mainly focused on the 2 first steps.
