During the current basic track at the School of Design Thinking at the HPI in Potsdam I had the pleasure to run several sessions with the students regarding the importance of prototyping during a design thinking project. For sure for early testing but also as important and powerful way of develop and iterate ideas inside the team. Sometimes without even words.
I combined this short input with several exercises, where the students created in several iterations and with very strikt time-boxing different prototypes based on a certain challenge.
Interesting to see how effective athe hand-over from a first version of a prototype to another team worked out in the end.
