Panel of CEOs choose their best business books

A panel of executives and CEO's choose their top 20 business books of all time.

Some on here I've enjoyed, others are new. I'm going to pick up some Drucker. I have read some of his articles in the Harvard Business Review and been impressed. He's really grounded and pragamatic in his approach often championing relationship managment as the key. Tsun Tsus art of war also features on the list. This is sometimes quite cryptic but remains a classic. It's required reading when joining some organisations.
