Part II of this volume includes three summary chapters. The first (Chapter 8), by Tanya Heikkila and Paul Cairney (2017), provides a comparison and critique of the theories in this anthology. Given the importance of the comparative approach in advancing policy process theory, in Chapter 9 Jale Tosun and Samuel Workman (2017) provide tips and strategies for using the theories to conduct comparative research. The final chapter, by Christopher M. Weible (2017), offers an overview of the status of the field and general strategies for moving forward and climbing upward.
