Here's the skinny...
This book is by far the easiest of all idea books to read, most relevant, most thorough, but potentially most dangerous. Before I make a couple critiques, don't let what I'm about to say dissuade you from buying this gem, these are just caveats and the book is still a deal!
Page 25 - Alcan/CocaCola and Ethnography: When I read this I though, "Great, I'll use ethnography to solve my innovation problems." Being the information pig that I am I checked this "idea" out with a professional, a doctor of Anthropology at the local university. We had a 30 minute chat and I came away with the thought "Alcan doesn't have a clue what they are talking about." What was described on page 25 was single variable observation, not ethnography. In fact, single variable observation has lead to problem after problem for marketers, Dr. "C" gave me these examples, 1) `Got Milk?' when marketed towards the Hispanic population translated into "Are you Lactating?" 2) McDonald's in parts of China had Ronald McDonald march in a parade, this was analogous to having the grim reaper march in the Santa Clause parade. 3) Chevy Nova in Mexico - we all know that one. And he gave me many other examples of major blunders that were directly attributed to single variable observation.
Page 47 - Hasbro and the "Alpha Pups": This is an excellent example of a major short coming with this book - there is no depth. The book summed up a major research and development initiative in a hundred or so words.
I chose the two examples because they are familiar ground for me. If you want to know how well a book is written analyze what was said against what you know. If there are faults then there are probably faults with the other sections. I can't fault the other sections because I'm not an expert on them or know an expert to discuss them with. Therefore there are probably other faults in the other articles as well. Is this a moot point because the book is intended to be an overview on a couple hundred techniques? Maybe. But then that's for the prospective readers to decide and measure their needs against. [...]
