Based on the classic policy cycle approach, key heuristics are presented that are currently used in the study of public policy and distinguishable policy styles. The selected frameworks include actor-centered institutionalism by Fritz Scharpf and Renate Mayntz, the advocacy coalitions framework by Paul Sabatier, the multiple streams framework by John Kingdon, as well as a summary of various approaches and considerations regarding policy learning. Helpful graphics and tables, along with detailed application examples, provide an easy entry into the subject and serve as a guide for writing academic papers in the field of policy research and policy analysis. The book serves as an introductory work in textbook style on the development, questions, and tools of policy analysis, aimed at first-year students in the field of politics.
