“Efficiency is concerned with doing things right. Effectiveness is doing the right things.”
Peter F. Drucker (1909-2005) was an Austrian-American management theorist, consultant, and author, widely considered the "father of modern management" for transforming it into a liberal art focused on human values, ethics, and societal impact. Born in Vienna, he fled Nazi Germany, immigrated to the U.S. in 1937, and became a prolific writer (39 books), teacher at New York University and Claremont Graduate University, and influential advisor to global corporations, popularizing concepts like Management by Objectives (MBO) and the knowledge worker.
