Organizational behavior (OB) is the study of how individuals, groups, and structures influence behavior within organizations and how that behavior affects their performance and effectiveness. The goals of OB are to understand employee behavior related to work and how it impacts outcomes like absenteeism, productivity, and management. OB applies this knowledge to make organizations operate more effectively. It examines behavior at the individual, group, and organizational levels and seeks to explain outcomes through an inputs-processes-outcomes model.
