This document provides an overview of an introductory chapter on organizational behavior. It defines organizational behavior as the field studying how individuals, groups, and structure influence behavior in organizations. The chapter outlines the major topics in organizational behavior including motivation, leadership, communication and discusses how OB draws from other social sciences like psychology, sociology, and anthropology. It notes that while general principles can help understand behavior, there are few absolutes given human complexity, and theories must account for situational factors. Managers face challenges in applying OB concepts given trends like globalization.
