I got to thinking about my favorite books from other genres besides fiction. Here are my top three business books:
Leadership and Self Deception: Getting Out of the Box by the Arbinger Institute. This book is written as a story about a manager that learns about being true to himself and to others. Very good.
The Five Dysfunctions of a Team: A Leadership Fable by Patrick M. Lencioni. If you have questions about why teams often don't work, this book pretty much covers it.
Finally, Good to Great: Why Some Companies Make the Leap...and Others Don't by Jim Collins. If you are considering reading Built to Last by the same author just skip it and read this prequel. The principle of "getting the right people on the bus" really rang true to me.
