In this lecture, we explore the ideas of Peter Drucker, often called the father of modern management. Drucker argued that the true purpose of business is to create a customer, and that innovation and responsibility are at the heart of management practice. We discuss his influence on concepts such as management by objectives, the rise of knowledge workers, and the ethical role of corporations in society. With examples from Intel, Apple, and Johnson & Johnson, the episode highlights how Drucker’s broad and pragmatic vision continues to shape how organizations think about strategy, purpose, and responsibility in a turbulent world.
