Administration involves setting policies, objectives, and plans for an organization, while management focuses on implementing those plans and coordinating organizational activities. Practically, managers perform both administrative and management functions, with higher-level managers spending more time on administration and lower-level managers focusing more on operational management. Public administration differs from private administration in that it operates within a legal and political framework, aims to serve public needs rather than profit, and is accountable to the public. It also typically involves larger-scale operations and provides essential services.
