How Competitive Forces Shape Strategy*
The essence of strategy formulation is coping with competition. Yet it is easy to view competition too narrowly and too pessimistically. While one sometimes hears execu-tives complaining to the contrary, intense competition in an industry is neither coinci-dence nor bad luck.
Moreover, in the fight for market share, competition is not manifested only in the other players. Rather, competition in an industry is rooted in its underlying economics, and competitive forces exist that go well beyond the established combatants in a partic-ular industry. Customers, suppliers, potential entrants, and substitute products are all competitors that may be more or less prominent or active depending on the industry.
The state of competition in an industry depends on five basic forces, which are di-agrammed in Figure 1. The collective strength of these forces determines the ultimate Figure 1
