John Hagel III, formerly a partner at McKinsey & Co. and now chief strategy officer for 12 Entrepreneuring Inc., has written the book on strategy — literally. He is the coauthor of Net Gain: Expanding Markets Through Virtual Communities (Harvard Business School Press, 1997) and of Net Worth: Shaping Markets When Customers Make the Rules (Harvard Business School Press, 1999) — two books that have shaped strategic thinking at countless firms. We asked Hagel to provide a reading list that focuses on Internet strategy. Here are his choices, along with his comments.
The Art of War, by Sun Tzu (Shambhala Publications, 1988). A fourth-century bc Chinese general offers his views on war. His emphasis on doing the least to accomplish the most foreshadows the importance of leverage in modern business strategy.
