As a noun, management refers to persons in supervisory roles who are responsible for getting work done through others. As a process, management involves planning, organizing, staffing, directing, and controlling. As a discipline, management is the study of principles and practices related to effectively achieving organizational goals. Management aims to optimize resources, minimize risks and costs, improve performance, and plan for the future growth and development of a business.
