A complexity theory perspective on politico-administrative systems : Insights from a systematic literature review

Complexity theory (CT) refers to a collection of concepts and heuristics that can be used to study the developments emerging from interactions between phenomena, actors, and events. CT has increasingly been utilized in the study of public administration and policy. However, there is no comprehensive analysis of empirical or other research focused on the functioning of political-administrative phenomena applying CT. This article reports the results of a systematic literature review demonstrating how CT has been applied in empirical research in different stages of the policy cycle: policy preparation, implementation, evaluation, and maintenance. The study reveals empirical research utilizing CT offers practical implications that can be categorized into four themes: enabling leadership, leveraging experimentation, the holistic perspective, and the humble approach.
