The study of public administration has always been closely linked to organization theory.
Since 1937 various efforts to develop organization theory had been baswd upon the concept that inducements given in exchange for contributions must be viewed in social and political terms.
For instance, organization theorist called Briton Urwick considered the principle of line and staffing as an essential aspect of organization theory.
He said staff aids helped in planning, expanding the brain power and will of the organization, but they do solely in the name of the authoritative commander, and by doing so do not violate the basic structure of the hierarchical organization.
