Don't just take my word for it, though. Many experts have had their say as well.
Woodrow Wilson was far more eloquent than me when defined public administration as the "detailed and systematic execution of public law" (Kettl & Fesier'2009'p.43). To paraphrase Leonard D. Whit,public administration is the efficient execution of public business (1926).H. George Fredericks and Camilla Stivers would add "socially equitable" to that definition. Combining the above experts' definitions with mine,public administration is the socially equitable execution of public law into action. However,if you ask Robert Parker and some other experts, they will say that.
