The original of the Napkin Method may be found in the imaginative work of Dan Roam, the award-receiving visual thinker and the author of “The Back of the Napkin: Solving Problems and Selling with Pictures.” Roam uses this technique to simplify abstract notions and thoughts into straightforward illustrations on the other side of a napkin. The Napkin Method was originally developed as a communication and problem-solving tool, but it has now evolved into a flexible productivity tip that can be used in variety of everyday situations.
