If you need a book that covers “Strategy 101,” this is the best possible book: The Strategy Book: How to Think and Act Strategically to Deliver Outstanding Results (2nd Edition) by Max McKeown. This book is highly digestible and written in plain English. You’ll like it because it includes some real examples and is quite up-to-date in terms of the breadth of topics addressed. I like this book because it’s not trying to sell a particular approach or point of view. This is your MBA course in a single, accessible book. What it is missing is some science—whatever the flavor (game theory, behavioral science, economics).
