This document provides an introduction to principles of management. It defines management as coordinating work through people to achieve goals efficiently and effectively. Studying management is important for understanding organizations. An organization requires people, processes, and a common purpose. Management can be viewed as both a science, with a body of organized knowledge, and an art that requires personal skills. Managers work with people to coordinate their activities and accomplish goals using interpersonal, informational, and decision-making roles. Approaches to management have evolved over time from classical approaches emphasizing efficiency to more modern approaches considering human and situational factors.
