Organizational behavior is the study of individual and group dynamics within organizations. It aims to understand, predict, and manage such behaviors. Understanding organizational behavior helps people become effective employees, team members, and managers by attaining needed competencies. Models of organizational behavior represent knowledge, summarize findings, and guide attention. They help explain why events occur and provide guidance for enacting change. There are three main types of models: descriptive, predictive, and prescriptive. Basic organizational behavior models examine individual, group, and organizational systems levels and their interactions.
