If you are a marketer and believe that you mostly is doing Promotion, then this book is for you. On the other hand, if you understand that marketing and sales are not opposites or even understand why R&D usually is under marketing (i.e. is reasonable well-educated), then this book seems to be a waste of time…

For all amateur-marketers out there, I'll give this one an OK mark, but for the rest, you ain't missing anything.
