Hello,

Public Administration :

can be broadly described as the development, implementation and study of branches of government policy. The pursuit of the public good by enhancing civil society, ensuring a well-run, fair, and effective public service are some of the goals of the field.

Public administration is carried out by public servants who work in public departments and agencies, at all levels of government, and perform a wide range of tasks. Public administrators collect and analyze data (statistics), monitor budgets, draft legislation, develop policy, and execute legally mandated government activities. Public administrators serve in many roles: ranging from "front-line" positions serving the public (e.g., peace officers, parole officers, border guards); administrators (e.g., auditors); analysts (e.g., policy analysts); and managers and executives of government branches and agencies.

Public administration is also an academic field. In comparison with related fields such as political science, public administration is relatively new, having emerged in the 19th century. Multidisciplinary in character, it draws on theories and concepts from political science, economics, sociology, administrative law, behavioural science, management and a range of related fields. The goals of the field of public administration are related to the democratic values of improving equality, justice, security, efficiency, effectiveness of public services usually in a non-profit, non-taxable venue; business administration, on the other hand, is primarily concerned with taxable profit. For a field built on concepts (accountability, governance, decentralization, clientele), these concepts are often ill-defined and typologies often ignore certain aspects of these concepts
