A firm creates value when it delivers benefits to buyers that justify a price above the cost of producing those benefits. Competitive advantage exists when a firm can deliver value more efficiently than rivals, or deliver unique value that rivals cannot match. This definition shifts attention away from market share, growth rates, and other popular metrics toward the fundamental economics of value creation. It forces managers to ask hard questions: What exactly do our buyers value? What are…
