I am not a designer . . . an engineer . . . or a marketing person . . . but this book was very interesting, wildly informative, intellectually accessible, and yes entertaining! As I see it . . . in life's various roles beyond those professional capacities mentioned above we are all designers/producers/consumers. So on any number of levels, this book is insightful and useful. It is ultimately a professional, industrial-strength, treatment on business products and programs - a genre I am admittedly under-qualified to critique - but as a dad, Sunday school teacher, a small business owner, and a curiosity freak, I was by truly charged by its implications in all aspects of my to-be-constructed-by-pictogram life.
