Michael E. Porter, Competitive Advantage: Creating and Sustaining Superior Performance (Repost)

The essential complement to the pathbreaking book Competitive Strategy, Michael E. Porter's Competitive Advantage explores the underpinnings of competitive advantage in the individual firm. With over 30 printings in English and translated into thirteen languages, this second volume in Porter's landmark trilogy describes how a firm actually gains an advantage over its rivals. Competitive Advantage introduces a whole new way of understanding what a firm does. Porter's groundbreaking concept of the value chain disaggregates a company into "activities," or the discrete functions or processes that represent the elemental building blocks of competitive advantage.
