Thinking with your hands

I was listening to a TED podcast this morning from a gentleman from IDEO. He described a design session where an IDEO team was meeting with surgeon's to discuss a new surgical instrument they would like developed. Someone from the design team left the room and in a few minutes returned with a dry erase marker taped to an empty film canister that was taped to a clothes pin in the rough shape of a gun. The designer gave it to the surgeon's who passed it around and begin offering very constructive feedback on how the device should sit in the hand, how it should be shaped, what it should do, etc. IDEO calls this behavior "thinking with your hands" (and this eventually turned into a real device).

It typically involves making many low-resolution prototypes very quickly. Often by bringing many found elements together in order to get to a solution...And so this behavior is all about quickly getting something into the real world and having your thinking advanced as a result.

This dovetails precisely with the Getting Real approach advocated by 37Signals. Tom Peters has been an advocate of this for years. And it explains why the Back of the Napkin approach of visual thinking works so well.

IDEO takes this idea seriously and has "protyping carts" around filled with Play-doh, tape, Legos, colored paper, markers, etc. ("the stuff we all had in pre-school") so desingers can begin prototyping objects whenever they want. They also apply this approach to designing a service experience through rapidly jumping into role-playing various scenarios.
