Chester Irving Barnard (November 7, 1886 – June 7, 1961) was an American business executive, public administrator, and the author of pioneering work in management theory and organizational studies. His landmark 1938 book, The Functions of the Executive, sets out a theory of organization and of the functions of executives in organizations. The book has been widely assigned in university courses in management theory and organizational sociology.

According to Barnard, organizations are generally not long-lived because they do not meet the two criteria necessary for survival: effectiveness and efficiency. Biography In his youth, Barnard worked on a farm, then working as a piano tuner, paid his way through high school at the Mount Hermon School.

Barnard joined the American Telephone and Telegraph Company (now AT&T) in 1909. In 1927, he became president of the New Jersey Bell Telephone Company.

End 1950s he was among the first members of the Society for General Systems Research.

Similarly most nations last for less than a century. The only organization that can claim a substantial age is the Roman Catholic Church. According to Barnard, organizations are not long-lived because they do not meet the two criteria necessary for survival: effectiveness and efficiency. Effectiveness, is defined the usual way: as being able to accomplish stated goals.
