Management can be defined as the process of planning, organizing, staffing, leading and controlling organizational resources to achieve organizational goals in an efficient and effective manner. It involves coordinating the efforts of people and using available resources to achieve desired goals. Management occurs at three levels in organizations - top level, middle level, and lower level. The key functions of management include planning, organizing, staffing, directing and controlling. Management is both a science and an art as it involves both a systematic body of knowledge as well as practical application of skills. Organizations must understand and adapt to various internal and external environmental factors that influence their operations.
