I loved The Back of the Napkin: Solving Problems and Selling Ideas with Pictures by Dan Roam. I highly recommend it to anyone who needs to solve problems or communicate their ideas.
From the inside flap:
Any problem can be made clearer with a picture, and any picture can be made using the same simple set of tools and rules.
THE BACK OF THE NAPKIN proves that thinking with pictures can help you discover and develop new ideas, solve problems in unexpected ways, and dramatically improve your ability to share your insights. This book will help you literally see the world in a new way.
The book is broken into four (4) sections:
- Introductions - Anytime, Anyone, Anywhere: Solving Problems with Pictures
- Discovering Ideas - Looking Better, Seeing Sharper, Imagining Further: Tools and Rules for Good Visual Thinking
- Developing Ideas - The Visual Thinking MBA: Putting Visual Thinking to Work
- Selling Ideas - It's Showtime
This book isn't about drawing or modeling. It is a way of decomposing problems and then communicating them quickly and clearly using a standardized set of visual thinking frameworks.
The end result is "The Visual Thinking Codex: a master list of problem-solving pictures." This codex helps select the appropriate visual illustration for your problem type.
Verdict: Buy this book and commit it to memory.
