Many business books are a form of utopian literature and should be treated as such. Given this premise, one would think that a book with a title like "Journey to the Emerald City" would be a top-notch business book as it suggests the authors might have a certain awareness of this genre.
Unfortunately, this in not the case here. Instead, this is yet another entry in the "book as selling tool" sweepstakes. In this sub-genre of the business book, the book is the foot-in-the-door for selling consulting services. Little more than a powerpoint presentation fleshed out with the usual miscellaneous facts and figures, these books are short on everything but jargon. They offer middle managers cozy, self-evident insights and simplistic advice that most company employees find insulting or at least insipid. (Around our office, the charts in the first chapter that show "non-aligned" and "aligned" processes and goals are considered a fine example of this facile and fallacious sub-genre as they keenly demonstrate the obvious in the most obvious fashion possible.)
Business books are not known for their sense of humor, certainly, because as we all know, business is extraordinarily serious. Yet, lack of wit and self-awareness are not virtures either. Nor is the plodding purposefulness with which the authors describe their "innovative" approach, although again, they are clearly in good company in this genre.
A shame really, especially since clearly the publishers felt strongly enough about the book to spend some extra bucks on shiny green foil on the jacket. Then again, perhaps the title is more apt than I take it to be. Like in the Wizard of Oz, we find there is no wizard behind the flashy curtain and special effects, but rather the usual seller of snake oil.
