Management is an organized body of knowledge. "This book," in Peter Drucker'swords, "tries to equip the manager with the understanding, the thinking, the knowledge and the skills for today'sand also tomorrow's jobs." This management classic has been developed and tested during more than thirty years of teaching management in universities, in executive programs and seminars and through the author's close work with managers as a consultant for large and small businesses, government agencies, hospitals and schools. Drucker discusses the tools and techniques of successful management practice that have been proven effective, and he makes them meaningful and easily accessible.
