According to Elton Mayo, Professor of Industrial Management, Harvard Business School the Hawthorne plant is "any company controlling many thousand workers tends to lack any satisfactory criterion of the actual value of its methods of dealing with people."

The term gets its name from a factory called the Hawthorne works where a series of experiments on factory workers were carried out between 1924 and 1932.

The term was coined in 1955 by Henry A. Landsberger when analyzing older experiments from 1924-1932 at the Hawthorne works (a western electric manufacturing facility outside Chicago). Hawthorne Works had commissioned a study to see if its workers would become more productive in higher or lower levels of light.
