Competition Demystified: A Radically Simplified Approach to Business Strategy

Porter identified a complex five-force model for studying competition in any market. But Greenwald argues that there is only one essential factor in determining competitive advantages: how easy it is for competitors to enter or expand in a given market. If a company can erect strong barriers to entry—through customer captivity, lower production costs, or economies of scale—it can manage these advantages, anticipate competitors’ moves, or achieve stability through bargaining and cooperation.

Greenwald draws on game theory to explain what you should do if barriers to entry are strong, weak, or nonexistent. He covers a wide range of examples, from retail to telecommunications to auction houses. And his lessons can be applied whether your business is dominated by a single huge player, a handful of roughly equal players, or no one at all.

Competition Demystified will give executives and strategic planners an indispensable new way to exploit competitive advantage and achieve exceptional profits. It is destined to become a management classic.
