An Overview of Organizational Behavior: Organizational behavior is the study of human behavior in organizational settings, the interface between human behavior and the organization, and the organization itself. The study of organizational behavior is important because organizations have a powerful influence over our lives. Serious interest in the study of management first developed around the beginning of this century. Two of the earliest approaches were scientific management (best represented by the work of Taylor) and classical organization theory (exemplified by the work of Weber). Organizational behavior began to emerge as a scientific discipline as a result of the Hawthorne studies. McGregor and Maslow led the human relations movement that grew from those studies. Contemporary organizational behavior attempts to describe, rather than prescribe, behavioral forces in organizations. Ties to psychology, sociology, anthropology, political science, economics, engineering, and medicine make organizational behavior an interdisciplinary field. The basic concepts of the field are divided into three categories: individual processes, interpersonal processes, and organizational processes and characteristics. Those categories form the framework for the organization of this book. Important contextual perspectives on the field of organizational behavior are the systems and contingency perspectives, interactionalism and contemporary applied perspectives.
