This study from Deloitte suggests that survivor bias and a lack of rigor discredit the "research" in books like "In Search of Excellence" and "Good to Great".

They claim that "success studies tend to rely exclusively on intuition to justify the noteworthiness" of the companies which are studied and go on and provide a pretty easy to understand explanation of why what is presented as the secret of success in innumerable business books is really no more significant than seeing "Elvis in a slice of pound cake" Mmmmmm.... pound cake...
Sure, they are shilling for their own research, but it is definitely worth a read. I've seen all sorts of organizations try to claim success as due to their particular efforts - sometimes to laughable levels which I can't repeat, but if you are a consumer of business practices or business "research" it is a necessary read. Snake-oil salesmen may be well intentioned, but sometimes they are just plain wrong.
As an aside, often I don't get a chance to read some of the more popular business books until their fad has passed. More often than not, the tide has turned on a number of the companies profiled and they have fallen from greatness. The lesson learned: life is fleeting. Make what you can from it while you can.
