Step-by-step explanation:
The Hawthorne studies are examples of the behavioral management approach. These studies, conducted at the Hawthorne Works of the Western Electric Company, found that employees' performance improved when they were observed and interacted with by researchers or supervisors. This phenomenon, known as the Hawthorne effect, showed that any change to a variable that increases the attention of the researchers on the participants can lead to an improvement in productivity. The results of these studies shifted the focus from the classical scientific management style, which emphasized efficiency and labor productivity without much regard for personal interaction, to recognizing the importance of human factors in the workplace.
