(via ma.tt) Watched a TED talk by Tom Wujec, who is an Autodesk fellow, about the "Marshmallow challenge" (http://marshmallowchallenge.com). Wujec talks about what you can learn from watching teams with different backgrounds collaborate on a design/engineering challenge. Prototype/refine (iterate) is generally a successful method. Introducing high stakes lowered results for non-informed (unprepared) teams but led to improved results for "informed" (prepared) teams who understood the benefit of iterative prototyping.
