I was intrigued by the concept of this book and decided to purchase it. I am very happy I did. Dan Roam's ideas are original and fresh and his framework has really got me thinking about ways to utilize his approach in my business, especially when trying to communicate complex ideas and issues.

I liked the fact that his concepts were simple although I've found them to be a bit challenging to implement, more than likely because it's not something I'm used to doing. I would recommend this book to anyone who is willing to challenge their conventional way of thinking and to step outside their comfort zone.

I've found this book to be one of the truly unique books about business that I have read and I've thoroughly enjoyed it.

A funny thing happened on the way to the boardroom--this book is for everyone trying to problem solve in a creative, and also prgamatic way. Oxymoron? Not so! This book teaches you how--
Right-brainers and left-brainers are both super stars in this book.

The book was not what I expected. I was thinking quick and dirty simple math formulae but what I found was something more robust and comprehensive. The book began with the 5 W's (Who, What, When, Where, Why...) and finished with process flow diagrams and XY charts. Examples of effective, simple, basic shapes are introduced at the beginning. Four steps of visual thinking are presented with examples. The thinking process of Looking vs. Seeing are presented in three separate chapters. These chapters show how to layout the most effective visual diagram tailored for the audience. The SQVID (Simple, Quality, Vision, Individual, Delta) method is presented enlarging the visual content methods.
The book is a concise course in data presentation/analysis. The chapters can be read at once or as needed. I suggest scanning the book for familiarization with the contents. Then cherry-pick or smorgasbord what you need, when you need it, for who you need it...
If you work in this kind of business situation or are a student with term papers and theses ahead then this book is for you.

You don't need to be able to draw like an artist to communicate and capture great ideas. This book eases you into overcoming your fear of drawing and jump in with simple sketches and annotations. Unleash your creative right-brain and get to work immediately with the tools Roam provides. I liked the book and use it in my business practice to help people discover the power the ideas we develop together. When the communication on paper begins with drawings, clients engage with me, the concepts come together quickly and momentum is formed.

"The Back of the Napkin" provides a methodology to quickly identify the underlying structure in apparent random, complex and nebulous problems/processes. As an American working in a foreign country, I found the graphical methods especially effective in creating an inclusive environment for all team members, including those with poor English skills.
