Peter Drucker is the greatest management thinker of all time, and his teachings are more relevant than ever. What is the reason for this? He was the first to demonstrate that management can be learned: being a manager is a profession, not a calling. And like no one else, Peter Drucker made it clear that managers have a social responsibility and that management is a societal endeavor—within companies, institutions, and administrations. This completely restructured and updated edition of "Management" contains Peter Drucker's complete management teachings, providing everything a leader needs today.
