Which one of the following is not a part of Hawthorne experiments?

The incorrect answer is Mass assembly room.

Key PointsHawthorne experiments"

• A group of researchers from the Harvard Business School led by Elton Mayo and Fritz Roethlisberger were asked to participate in the investigations in 1927 at the Hawthorne Works of the Western Electric Company in Chicago.
• The trial continued until 1932.
• The Hawthorne Experiment demonstrated that workers' productivity is not solely dependent on the physical environment in which they work and the amount of money they are paid in compensation.
• Employee happiness with their working environment has a significant impact on their productivity.
• Mayo believed that when assessing productivity efficiency, rational criteria were significantly less crucial than emotional factors.

Important PointsThe Hawthorne experiments consists of four parts. 

Illumination Experiment: 

• To determine the link between output and illumination, this experiment was carried out.
• The output rose along with the rise in light intensity.
• Even after progressively lowering the illumination to the desired level, the output continued to trend upward.
• Therefore, it was determined that there is no consistent correlation between worker output and factory illumination.
• There must be another element that had an impact on production.

Relay Assembly Test Room Experiment: 

• This phase sought to understand the effects of lighting on production as well as other elements including working hours, rest periods, and other physical conditions

Interviewing Programme: 

• The goal of this programme was to conduct a thorough analysis of the attitudes of the employees in order to understand the significance that their "working condition" has for them.
• Numerous employees were questioned by the researchers about their views on their jobs, working environment, and management.
• In the beginning, a direct strategy was employed, in which interviewees answered questions deemed crucial by management and researchers.
• The researchers noticed that the workers' responses were reserved. Consequently, an indirect strategy was used in place of this approach, where the interviewer merely listened to what the workers had to say.
• The results supported the significance of social aspects in the overall workplace.

Bank Wiring Test Room Experiment: Finding of this study are as follows:

• Each person was limiting their productivity, the gang established its own "unofficial" performance requirement. 
• Over time, individual production stayed largely unchanged, Informal groups are crucial to an organization's operation.
