Administration involves planning, organizing, directing, controlling and coordinating people and resources to efficiently achieve organizational goals. It applies to all types and sizes of organizations across both lucrative and non-lucrative sectors. Effective administration balances productivity, efficiency and efficacy. While it draws from scientific principles, administration also involves interpersonal and conceptual skills, making it both an art and a science. Key theorists like Taylor, Fayol, Mayo and Mintzberg contributed important foundations and perspectives on the nature and functions of administration.
