Peter Drucker, the most profound management thinker in history, has indefatigably pointed out that “there is only one valid definition of business purpose: to create a customer” (Flaherty, 1999: 131). This is known as the marketing concept. The purpose of any organization—from a governmental agency or nonprofit foundation, to a corporation or a church—exists to create results outside of itself. The result of a school is an educated student, as is a cured patient for a hospital, or a saved soul for a church. A business exists to create wealth for its customers.
