The Hawthorne Effect is a phenomenon where individuals modify their behavior in response to being observed. This can result in temporary increases in productivity. The effect was first observed in a series of experiments conducted between 1924 and 1932 at the Hawthorne Works, a Western Electric plant in Cicero, Illinois. The study found that changes in work structure, such as changes in rest periods, led to increases in productivity. Additionally, the study found that the novelty of being research subjects and the increased attention from being part of the study led to temporary increases in workers’ productivity. Industrial engineers should be aware of this phenomenon when conducting experiments or observing workers, as it can affect the outcome of the study.”
