This document discusses industry competition and Porter's five forces framework. It begins with definitions of industry and the structure-conduct-performance model. It then explains Porter's five competitive forces that shape industry competition - the threat of new entrants, power of suppliers and buyers, threat of substitutes, and rivalry among existing competitors. The document also discusses generic strategies of cost leadership, differentiation, focus, and speed. Finally, it covers the tensions between global integration and local responsiveness, and how the integration-responsiveness grid can help companies address these pressures.
