"Dan Roam's The Back of the Napkin, a BusinessWeek bestseller, taught readers the power of brainstorming and communicating with pictures. It presented a new and exciting way to solve all kinds of problems-from the boardroom to the sales floor to the cubicle jungle.

The companion workbook, Unfolding the Napkin, helps readers put Roam's principles into practice with step-by-step guidelines. It's filled with detailed case studies, guided do-it-yourself exercises, and plenty of blank space for drawing. Roam structured the book as a complete four-day visual-thinking seminar, taking readers step-by-step from "I can't draw" to "Here is the picture I drew that I think will save the world."
