"Good to Great"

Its a book written by the famed author Jim Collins who had also authored "Built to Last". I have not read that one though. Its an amazing book providing concrete analysis of great companies and trying to find a pattern in their success.
Some findings go against the conventional wisdom and that is what makes it different. Its an eye-opener, sort of enlightening. I have started looking for those signs in my current organization to see if it will ever become great. Long way to go .... but we will reach there someday :).
Plus you can apply some concepts to yourself and figure out what does it take to be great :).

Happy reading!!
