Therefore, to understand the context of public policy as a field, it is essential to explore its root developments in public administration from epistemological and chronological perspectives. This chapter is a review study referring to main scholarly works including books, academic articles, and studies. The chapter first helps researchers and students in comprehending the evolution of public administration in its four main stages including classical public administration, new public administration, new public management, and new public governance. Second, the chapter presents a general overview of the evolution of the public policy field with particular attention paid to the concepts of Harold Lasswell who is seen as the father of public policy. The chapter then discusses different definitions of public policy. Various classifications of public policy are also investigated. The chapter ends with a critical discussion of the stages model (heuristics).
