Written by the leaders of Bain & Company's worldwide strategy practice, and based on a 10-year study of 2,000 companies, this book argues that a timeless strategic principle focusing on a central profit area remains the key source of competitive advantage and the only viable platform for successful expansion.
This book was OKish. (I'd give it 2.5 stars if allowed to) The main thesis is that your business should figure out what it's good at and focus on that. When you want to expand, focus in adjacent markets where you can leverage what you're good at. The book is very down on diverse conglomerates.
Which is all fine and such, but the book itself was kind of dull and repetitive. Also, being written in 2001, it has some amusing bits: - It quotes Mitt Romney! (the book was written by people at Bain) - It isn't so sure how Amazon's move to sell other things than books is going to work. - The best part was the few pages on how Enron(!) does so well! There's also a few positive mentions of WorldCom.
Joint first in my list of business books. Provides an excellent rationale as to why chasing every potential opportunity can be so dangerous and the merit of self-reinforcing focus.
