Our first edition championed the cause of the open system approach to the study of organizations. Today that point of view has gained wide acceptance in organizational research and theorizing. Research is no longer contained within the boundaries of a single organization but crosses those borders to deal with environmental forces, relationships with other systems, and the effects of organizations on individual members as human beings and members of the larger society. That social psychological principles can be applied to all forms of collective organized effort is now acknowledged in many disciplines. Industrial psychology has moved toward becoming organizational psychology and not only studies behavior of people in many organizational settings but on occasion recognizes organizational or system variables in shaping that behavior.
