Organizational behavior (OB) or organisational behaviour is the: 'study of human behavior in organizational settings, the interface between human behavior and the organization, and the organization itself'. OB research can be categorized in at least three ways: Organizational behavior (OB) or organisational behaviour is the: 'study of human behavior in organizational settings, the interface between human behavior and the organization, and the organization itself'. OB research can be categorized in at least three ways: Chester Barnard recognized that individuals behave differently when acting in their organizational role than when acting separately from the organization. Organizational behavior researchers study the behavior of individuals primarily in their organizational roles. One of the main goals of organizational behavior is 'to revitalize organizational theory and develop a better conceptualization of organizational life'. Miner (2006) mentioned that 'there is a certain arbitrariness' in identifying a 'point at which organizational behavior became established as a distinct discipline' (p. 56), suggesting that it could have emerged in the 1940s or 1950s. He also underlined the fact that the industrial psychology division of the American Psychological Association did not add 'organizational' to its name until 1970, 'long after organizational behavior had clearly come into existence' (p. 56), noting that a similar situation arose in sociology. Although there are similarities and differences between the two disciplines, there is still confusion around differentiating organizational behavior and organizational psychology. As a multi-disciplinary, organizational behavior has been influenced by developments in a number of related disciplines including: Sociology, industrial/organizational psychology, and economics. The Industrial Revolution is a period from the 1760s where new technologies resulted in the adoption of new manufacturing techniques and increased mechanization. In his famous iron cage metaphor, Max Weber raised concerns over the reduction in religious and vocational work experiences. Weber claimed that the Industrial Revolution's focus on efficiency constrained the worker to a kind of 'prison' and 'stripped a worker of their individuality'. The significant social and cultural changes caused by the Industrial Revolution also gave rise to new forms of organization. Weber analyzed one of these organizations and came to the conclusion that bureaucracy was 'an organization that rested on rational-legal principles and maximized technical efficiency.' A number of OB practitioners documented their ideas about management and organisation. The best known theories today originate from Henri Fayol, Chester Barnard, and Mary Parker Follet. All three of them drew from their experience to develop a model of effective organizational management, and each of their theories independently shared a focus on human behavior and motivation. One of the first management consultants, Frederick Taylor, was a 19th-century engineer who applied an approach known as the scientific management. Taylor advocated for maximizing task efficiency through the scientific method. The scientific method was further refined by Lillian and Frank Gilbreth, who utilized time and motion study to further improve worker efficiency. In the early 20th century the idea of Fordism emerged. Named after automobile mogul Henry Ford, the method relied on the standardization of production through the use of assembly lines. This allowed unskilled workers to produce complex products efficiently. Sorenson later clarified that Fordism developed independently of Taylor. Fordism can be explained as the application of bureaucratic and scientific management principles to whole manufacturing process. The success of the scientific method and Fordism resulted in the widespread adoption of these methods. In the 1920s, the Hawthorne Works Western Electric factory commissioned the first of what was to become known as the Hawthorne Studies. These studies initially adhered to the traditional scientific method, but also investigated whether workers would be more productive with higher or lower lighting levels. The results showed that regardless of lighting levels, when workers were being studied, productivity increased, but when the studies ended, worker productivity would return to normal. In following experiments, Elton Mayo concluded that job performance and the so-called Hawthorne Effect was strongly correlated to social relationships and job content. Following the Hawthorne Studies motivation became a focal point in the OB community. A range of theories emerged in the 1950s and 1960s and include theories from notable OB researchers such as: Frederick Herzberg, Abraham Maslow, David McClelland, Victor Vroom, and Douglas McGregor. These theories underline employee motivation, work performance, and job satisfaction. Herbert Simon's Administrative Behavior introduced a number of important OB concepts, most notably decision-making. Simon, along with Chester Barnard, argued that people make decisions differently inside an organization when compared to their decisions outside of an organization. While classical economic theories assume that people are rational decision-makers, Simon argued a contrary point. He argued that cognition is limited because of bounded rationality For example, decision-makers often employ satisficing, the process of utilizing the first marginally acceptable solution rather than the most optimal solution. Simon was awarded the Nobel Prize in Economics for his work on organizational decision-making. In the 1960s and 1970s, the field started to become more quantitative and resource dependent. This gave rise to contingency theory, institutional theory, and organizational ecology. Starting in the 1980s, cultural explanations of organizations and organizational change became areas of study, in concert with fields such as anthropology, psychology and sociology. Research in and the teaching of OB primarily takes place in university management departments in colleges of business. Sometimes OB topics are taught in industrial and organizational psychology graduate programs.
