The original edition of Management: Tasks, Responsibilities, Practices published in 1973. Peter Drucker continued to write, teach, and act as a consultant to management for thirty-two years after the publication of the book. This edition updates the original by integrating it with the work published on this subject from 1974 to 2005. All of the sources used to revise this book, except for the content of this chapter, are from materials housed at The Drucker Institute, Claremont, California, and are copyrighted by Peter F. Drucker.
My task was one of synthesizing this new material with the original material, always replacing the old with the new. In addition, I eliminated obsolescent material from the original edition and updated specific examples whenever possible.
