Administration is the process of managing and coordinating resources, people, and activities within an organization to achieve its goals efficiently and effectively. It involves decision-making, planning, organizing, staffing, directing, and controlling various aspects of an organization's operations. There are three main types of administration: centralized administration where decision-making authority is concentrated at the top; individual administration where each department is self-managed; and semi-centralized administration which balances central control with decentralized decision-making. Effective administration provides structure, goal achievement, coordinated decision-making, compliance, and adaptability to help organizations function properly and thrive.
