This document provides an introduction to management and organizations. It defines what managers do, which includes coordinating work, overseeing employees, and establishing goals. Managers are classified into three levels: first-line managers oversee employees, middle managers oversee other managers, and top managers make organization-wide decisions. The functions of management are planning, organizing, leading, and controlling. Studying management is valuable because management skills are needed universally, both managers and employees need management skills, and management careers can be rewarding but also challenging.
