MY RATING: **** (4 out of 5 stars)
The back of the Napkin is a very useful overview of using white board drawings in presentations and to solve problems. Visual approach to problem solving has always been one of my interests, and although this book does not have the same range as Tufte’s classic books on informational design, it has a lot of very practical useful information. The tone of this small, illustrated volume is rather chatty, and very informal, which makes for a quick and entertaining (as well as useful) read. Although this was not the authors intent, many of his suggestions, techniques and ideas can easily be adapted and used to improve PowerPoint or Keynote presentations as well (of course, he suggests that letting go of PP is the way to go). Combining his ideas with electronic “smartboartds” opens up a whole range of new, exciting, instructional possibilities.
