My boss is addicted to books like this. Instead of getting out and actually finding out how his staff feel about their jobs, their coworkers, their customers and the company, he devours trite little one-size-fits-all management books like this one. His office is full of them, and he orders them by the case to hand out to his favorite people (instead of pay raises, oh goody).
The one lesson to be learned from Ken Blanchard, et al., is that if you really want to to make lots of money in business, put together a how-to book on management full of trite tips like "show your customers you really care", and "encourage your employees to be creative", and follow up with a roadshow of seminars and training sessions.
Offer motivational posters, keyrings, ball hats and mouse pads with content free inspirational messages for bosses to hand out to employees instead of actual perks and benefits, and offer fancy diplomas suitable for framing for those unlucky enough to be forced to attend seminars on their own time.
The ideas in this book are really nothing more than vaseline.
