This is bad, very bad. Anyone that believes that management decisionmaking is based on the application of mathematical formulas is out of touch of reality. Even worse, it is badly written and I can't understand why this book is typeset to look like it just came out of an 1980s Epson printer (with one font!). Other words that may be used to describe this book is : academic masturbation.
I pity my wife, as she had to utilse this book when she went to the university. It also makes my decision to get a British MBA in retrospect seem like an enlightened idea. Anyway, this is pure trash in all respects, avoid at all costs!
