Yoffie (international business administration, Harvard Business School) and Kwak (research associate, Harvard Business School) use examples from companies such as Wal-Mart, Charles Schwab, Palm Computing, and RealNetworks to illustrate the ways that modern business strategy is analogous to Judo strategy, namely: use your opponents' size and strength to bring them down. The first three chapters lay out the principles of Judo strategy, movement, balance, and leverage, while the second section offers case examples of business people the authors call Judo Masters.
