Like management science, Organisational behaviour covers the relationship between the individual and his organisation. However, it differs in that it is mostly a descriptive discipline, while management science is more of a predictive discipline, based on the theoretical notions of power, social structures and social systems. Organisational psychology covers the individual and his formation, while Organisational behaviour covers the whole organisation. Organisational psychology includes elements from both, and Organisational behaviour as a new discipline is an attempt to create a more general discipline. It is likely that Organisational behaviour will also include elements from Organisational Psychology, because it is in an evolutionary process of development.
Organisational behaviour was originally a part of organisational psychology. After it became clear that organisational psychology had become too specialized, the new discipline was created. It is a more general term than Organizational Psychology, which focuses on the individual and the development of the individual. Organisational behaviour is also a special type of organizational behaviour.
Organisational behaviour is concerned with the way an organisation is run, how people in the organisation interact with each other, the way it reacts to changes in its environment and how it is managed. It is concerned with performance, morale, public relations, group norms, and group dynamics.
Organisational behaviour is a very broad, and mainly descriptive, field in psychology. It includes all forms of social behaviour, but excludes all kinds of experimental design. It is an a posteriori discipline, developed after management science had reached its highest point of development.
Organisational behaviour is a very broad discipline, and covers almost every subject in psychology. The discipline is very general, and it does not have an exact definition. Nevertheless, the Journal of Organizational Behavior 827ec27edc
