Hawthorne Studies refer to a set of experiments that were conducted before second world war in the USA. These studies played a major role in emphasizing the human dimension in an organization during the times when the evolution of different managements thoughts was taking place. This article gives details about those experiments, their implications as well as the criticism they faced. Using a study group other experiments were conducted hawthorne experiments focus on to examine what effect of monotony and fatigue on productivity and how to control those using variables such as rest breaks, work hours and incentives. Experimental research methods originated from behavioral research and are largely rooted in the field of psychology. Experimental research has been a highly effective research approach and has led to many groundbreaking findings in behavioral science in the 20th century.
The problems of workers could not be solved by taking one factor i.e. management could not achieve the results by emphasizing one aspect. All the things should be discussed and decision be taken for improving the whole situation. A balanced approach to the whole situation can show better results. Experiments have shown that the output increases when workers are explained the logic behind various decisions and their participation in decision making brings better results.
Changing a variable usually increased productivity, even if the variable was just a change back to the original condition. Researchers concluded that the employees worked harder because they thought they were being monitored individually. Researchers hypothesized that choosing one’s own coworkers, working as a group, being treated as special , and having a sympathetic supervisor were the real reasons for the productivity increase.
What is Hawthorne Experiment? Theory by Elton Mayo, 4 Phases
The aptitudes of individuals are imperfect predictors of job performance. Although such measures may give some indication of the physical and mental potential of the individual, the amount of work produced is strongly influenced by social factors. Perhaps unsurprisingly, the productivity of the workers who got more light increased much more than that of the control group.
On the first experiment workers were put on piece-work salary where they were paid on each part they produced, as a result the output increased. On the second experiment the workers were given 2 rest pauses of 5 minutes each for 5 weeks and again output went up. The third experiment further increased the pauses to 10 min and the output went up sharply. For the fourth experiments a 6, 5 min breaks were given and output fell slightly as the workers complained that the work rhythm was broken. On the fifth experiments conditions for experiment three were repeated but this time a free hot meal was given by the company and output wen up again.at the sixth experiment, workers were dismissed at 4.30p.m. This experiment was conducted to establish relationship between output and illumination.
Team meeting are to be held which allows the worker to give out his opinion and feel important by contributing his ideas to the organisation. Experimental research also requires strict control of factors that may influence the dependent variables. That is, except the independent variables, any factor that may have an impact on the dependent variables, often called potential confounding variables, needs to be kept the same under different experiment conditions.
He was consulted when the researchers of the Hawthorne plant couldn’t derive any conclusion from the illumination studies. In order to do so, the researchers of the company along with their new team members began the second experiment. During the Hawthorne studies, it’s possible that the workers received feedback on their productivity as part of the study. That extra observation and feedback could play into increased productivity.
He emphasized the management and technical aspects of quality control and developed a 10-step approach to quality management. He advocated developing processes for quality control, quality improvement, and quality breakthroughs. The researchers devised the first version of the guideline by analyzing a previous internal Microsoft study on code review practices, and by referring to academic literature.
They developed a feeling of stability and a sense of belongings. Since there was more freedom of work, they developed a sense of responsibility and self-discipline. The relationship between supervisor and workers became close and friendly. When the subjects experiencing the intervention and those in the control group are treated in the same manner in an experiment, the Hawthorne effect would likely influence both the groups equivalently. Another study sought to determine whether the Hawthorne effect actually exists, and if so under what conditions it does, and how large it could be (McCambridge, Witton & Elbourne, 2014). In a separate study conducted between 1927 and 1932, six women working together to assemble telephone relays were observed .
- In order to achieve participation, effective two-way communication network is essential.
- However, Jenny’s work environment was much different in that she worked closely with her coworkers and manager, a factor that Jenny felt increased her level of productivity.
- Performance feedback- This refers to information from an employer about how an employee performs.
- When the intensity of illumination decreased, the production continued to increase in both the groups.
Many employers try to make employees feel as though they are an integral part of the company. So people improve their work behaviour based on a change in their work environment, not in response to the nature of the change itself. In the case of the Hawthorne experiments, workers increased their productivity because the presence of the researchers had a motivational effect on them. Because the experiments originally sought out to study the effects of physical conditions on productivity, the researchers began the experiments by increasing the lighting in the work area of a group of workers. Another group of workers, whose lighting was not changed, served as a control group.
Observation may become a variable of its own that researchers have to account for when setting up or conducting a study. Game theory is the study of strategic decision making between individuals. The Hawthorne effect occurs when individuals change their behaviour in reaction to being observed or watched.
Social and Psychological needs must also be satisfied in order to increase productivity. Mayo pointed out that workers were not simply cogs, in the machinery, instead the employee morale can have profound effects on productivity. Human and social motivation can play even a greater role than mere monitory incentives in moving or motivating and managing employee group. The position or status of worker in the company is a reference from which the worker assigns meaning and value to the events, objects and features of his environment such as hours of work, wages, etc. The interview programme gave valuable insights about the human behaviour in the company.
Strategic Human Resources Management
The business can be inspired by mental and social needs since its conduct is additionally affected by sentiments, feelings, and perspectives. Consequently, monetary impetuses are by all accounts not the only strategy to propel individuals. The analysts say that the answers of the workers were monitored. Consequently, this approach was supplanted by a roundabout method, where the questioner essentially paid attention to what the workers needed to say.
It seemed that increased attention from supervisors could improve job performance. The company had sought to ascertain whether there was a relationship between productivity and the work environments (e.g., level of lighting in a factory). The Hawthorne effect refers to the increase in the performance of individuals who are noticed, watched, and paid attention to by researchers or supervisors. The legacy of the Hawthorne studies lives on as we continue to regard social and human relations as crucial aspects of business management. The relay assembly room experiment, which involved five female test subjects and tested several environmental factors, including break times and work hours. She was in Tom’s graduating class but is employed at The Force Technology, a direct competitor of Trekkie Technology.
The Hawthorne Effect has become a well-known term and is often studied in industrial and organizational psychology. In spite of the general popularity and acceptance of the concept, there has been much controversy over the years about whether the results of the initial studies were exaggerated or over-emphasized. Is a general term describing the effects of unequal treatment between study groups. There are two subtypes of performance bias—namely, the Hawthorne effect and the John Henry effect. Sustaining contact with participants over time reduces participant reactivity and improves the quality of data collection. A temporary improvement in performance resulting from participation in a research study for the first time is known as a novelty effect.
Hawthorne studies occurred in the 1920s in Illinois and were designed to explore avenues to increase worker productivity. The Hawthorne researchers became more and more interested in the informal groups that workers formed. They found out that there is a group life among the workers – independent of the organizational relationships. They also noticed that the relations supervisors develop with workers affect how workers carry out their tasks. Turning to empirical observation, we are confronted with a puzzling finding. In the UK, for example, the latest Workplace Employee Relations Survey in 1998 (Cully et al.

Other Experiments in the Hawthorne Studies
When recruiting participants, prescreening should be conducted to make the participants in different groups as homogeneous as possible. When confounding factors are inevitable, specific data analysis methods can be applied so that the impact of the confounding factors can be filtered out. A common method for this purpose is the analysis of covariables. The Hawthorne experiments are a backdrop for diverse studies assessing the impact of treatment and experimentation on human and organizational performance. We propose that the Hawthorne effect can be viewed as an active construct to develop a coherent strategy for performance improvement.
As part of the experiment, the women were given special privileges such as periodic breaks from work, free lunches and pay increase incentives. In 1933 Mayo wrote The Human Problems of an Industrial Civilization which emphasized the importance of focusing on the human and social needs in management theory. In this volume, he noted the influence that the presence of the researchers had on the resulting increase in productivity. Some of those most significantly involved in the experiments were Elton Mayo, a professor at Harvard Business School, along with his assistant Fritz J. Roethlisberger. Mayo and Roethlisberger also carried out about 20,000 interviews with employees. The goal of the experiments and interviews was to better understand the factors that contributed to productivity, especially as related to the human needs of the industrial workers.
