Electrifying in its simplicity - like all great breakthroughs - COMPETITIVE STRATEGY captures the complexity of industry competition in five underlying forces. Author Michael Porter introduces one of the most powerful competitive tools yet developed: his three generic strategies - lowest cost, differentiation, and focus - which bring structure to the task of strategic positioning. He shows how competitive advantage can be defined in terms of relative cost and relative prices, thus linking it directly to profitability, and presents a whole new perspective on how profit is created and divided. More than a million managers in both large and small companies, investment analysts, consultants, students, and scholars throughout the world have internalised Porter's ideas and applied them to assess industries, understand competitors and choose competitive positions. COMPETITIVE STRATEGY has filled a void in management thinking. It provides an enduring foundation and grounding point on which all subsequent work can be built. Porter's rich frameworks and deep insights comprise a sophisticated view of competition unsurpassed in the last quarter-century.
