Efficiency is doing things right; effectiveness is doing the right things. – Peter Drucker

Peter Drucker  (November 19, 1909 – November 11, 2005) is considered the father and founder of modern management. He was an Austrian-born American management consultant, author, and educator, whose writings contributed to the philosophical and practical foundations of the modern business corporation.

He is one of the best-known and most widely influential thinkers and writers on the subject of management theory and practice. His writings have predicted many of the major developments of the late twentieth century, including privatization and decentralization; the rise of Japan to economic world power; the decisive importance of marketing; and the emergence of the information society with its necessity of lifelong learning.

‘In most areas of intellectual life nobody can quite agree who is top dog. In management theory, however, there is no dispute. Peter Drucker has produced groundbreaking work in every aspect of the field.’ – Good guru guide’, Economist, 25 December–7 January 1994.

All results are on the outside. The inside is only cost and effort. – Peter Drucker

 From 1971 until his death, he was the Clarke Professor of Social Science and Management at Claremont. Claremont Graduate University’s management school was named the Peter F. Drucker Graduate School of Management in his honor in 1987 (later renamed the Peter F. Drucker and Masatoshi Ito Graduate School of Management). He established the Drucker Archives at Claremont Graduate University in 1999; the Archives became the Drucker Institute in 2006. Drucker taught his last class in 2002 at age 92. He continued to act as a consultant to businesses and nonprofit organizations well into his nineties.
