Organizational behavior is concerned with emerging realities in the workplace like knowledge replacing infrastructure and self-leadership superseding command-control management. It studies human behavior as individuals and in groups within organizations to identify ways people can act more effectively. Organizational behavior encompasses studying organizations from multiple viewpoints at the individual, group, and organizational levels to provide tools to describe, understand, and predict employee behavior. The goals are to describe behavior under various conditions, understand why people act as they do, and predict future behavior.
