I think that this worked for two major reasons. The first was that the students spent time in Nepal, on the ground, developing empathy. They listened more than they spoke. What they learned sparked the realization that a more efficient incubator wasn’t enough–they needed to rethink the entire product. Listening with both their ears and eyes led to the short-list of design constraints above. Second, the students were stubborn and refused to negotiate on any of the requirements.
