Drucker also taught us about the importance of management by objectives, and the role of strengthening organizations to strengthen society. As a young Jewish boy growing up in post-WWI Austria, he didn’t think he had much of a future there. So he left for America in 1945 as a young man after working as London, and got a job as a management consultant to Alfred Sloan, chairman of General Motors. Drucker was astute and made profound observations that had been lost in the sands of time. He encourages every business to get in the mud of its customer and clearly communicate your difference. His quote "The purpose of business is to create a customer, the business enterprise has two - and only two - basic functions: marketing and innovation. Marketing and innovation produce results; all the rest are costs." His lectures were fundamentally about the role of society, ethics and culture. Without it you really have nothing to lean on. Customer satisfaction, employee engagement and development, innovation, social responsibility and financial strength. He also believed that companies worked better decentralized. Those were Drucker’s key principles.
