Hawthorne Experiments:

An experiment was done in Western Electric Company from 1924 to 1933 alongwith HBS. The methodololgy was to divide the shop floor workers in to 2 different groups, one the control group & the other being of Test Group.

The studies originally looked into whether workers were more responsive and worked more efficiently under certain environmental conditions, such as improved lighting. The results were surprising: Mayo and Roethlisberger found that workers were more responsive to social factors—such as the people they worked with on a team and the amount of interest their manager had in their work—than the factors (lighting, etc.) the researchers had gone in to inspect.

The Hawthorne studies discovered that workers were highly responsive to additional attention from their managers and the feeling that their managers actually cared about, and were interested in, their work. The studies also found that although financial motives are important, social issues are equally important factors in worker productivity.

There were a number of other experiments conducted in the Hawthorne studies, including one in which two women were chosen as test subjects and were then asked to choose four other workers to join the test group. Together, the women worked assembling telephone relays in a separate room over the course of five years (1927–1932). Their output was measured during this time—at first, in secret. It started two weeks before moving the women to an experiment room and continued throughout the study. In the experiment room, they had a supervisor who discussed changes with them and, at times, used the women’s suggestions. The researchers then spent five years measuring how different variables impacted both the group’s and the individuals’ productivity. Some of the variables included giving two five-minute breaks (after a discussion with the group on the best length of time), and then changing to two 10-minute breaks (not the preference of the group).

The Hawthorne studies showed that people’s work performance is dependent on social issues and job satisfaction, and that monetary incentives and good working conditions are generally less important in improving employee

productivity than meeting individuals’ need and desire to belong to a group and be included in decision making and work.
