There's no faster, cheaper prototype in the world than a sketch on a sheet of paper. What's unclear in words is suddenly crystal clear in a sketch, and you--and your team--can tackle problems in entirely new ways. Play around with ideas. Document your process. Think on paper. Visual thinking brings a whole new power to work.

Think you can't draw? Don't worry! The simplest sketches are the most effective at communication and problem solving, so you can begin drawing in less time than your average coffee break. Pictures and visual communication harken back to the stone age for good reason--they're natural, they're quick, and they work. And they'll work for you.

If you're looking for the next tool to help you solve your hardest (and most interesting) challenges at work, try a paper and pencil. This book teaches you how to use them well--and have a bit of fun along the way.
