Peter Drucker is widely considered the founder of modern management. He developed concepts still relevant to quality professionals today. Drucker believed the purpose of a business is to create customers by delivering value, not just to make a profit. He argued traditional cost accounting focuses too much on short-term profits and not enough on long-term value creation. Drucker emphasized the importance of measuring economic value added over profits to truly understand if an organization is creating wealth. He saw customers, not internal departments, as the only true profit centers for a business.
