As one of the Product Discovery facilitators at D·Labs I came across some mind-blowing revelations while testing product prototypes in real world. From leaking caps on whiskey tasting packs to printout reports being unreadable by chemical company technician in the lab. My aim is to demonstrate the power of simple ways to test parts of complex products in order to make them more relevant. Lots of picutes, a few words. Hopefully some laughs.
