Competitive Advantage : Creating and Sustaining Superior Performance

Abstract

Competitive Advantage introduces a tool that may be used to diagnose and enhance competitive advantage: the value chain. Value-chain analysis allows the manager to separate the underlying activities a firm performs in designing, producing, marketing, and distributing its product or service. It is these activities from which competitive advantage ultimately stems. By showing how all the firm's activities can be examined in this integrated way, Porter provides a practical perspective on competitive strategy.
