Summary and Keywords
As a part of the policy process, implementation follows policy as formulated and decided upon. Three aspects can be distinguished as inherent to the term implementation. The first one regards the temporal order in which implementation in a policy process takes place. The second aspect concerns the causal logic, while the third one is about the form of authority. Policy implementation is looked at and talked about from two fundamentally contrasting perspectives. One can be called an “ideal” perspective, the other a realistic one. “Ideal” stands here for a use of the term implementation without further reflection; the phenomena the term refers to are taken for granted. By contrast, the alternative perspective can be labeled as a realistic one. This perspective is a construction as well, but instead of taking things for granted it invites for empirical observation and testing.
From an ideal perspective implementation is viewed as following instructions. Implementation is seen as a separate stage, identifiable as such. Inputs are supposed to determine outputs, while authority is exercised in a hierarchical relationship. From a realistic perspective implementation is seen as practice. It is approached as a multilevel phenomenon. Results of a policy process are explained by a variety of factors and social mechanisms. Authority is exercised as based on various sources. Both the view on implementation as following instructions and its realistic opposite shed a relevant light on implementation and its place in the policy process. Each view can be found in the practice as well as the study of the policy process. In the expectations about national politics the view on implementation as following instructions may be more observed than the alternative view, while at the street level of government the opposite can be supposed. However, these concern empirical questions.
As far as implementation research is concerned, the normative appeal of the assumptions underlying the view on implementation as following instructions makes that view still occurring. At the same time, these assumptions have been challenged rather fundamentally, both at a theoretical and empirical level. The opposite character of the two views has consequences for the ways implementation and its place within the policy process are understood, but also for the ways in which variation in the results of policy processes is explained. Ultimately, understanding and explaining those results are enhanced when an approach is adopted in which elements from both views have been incorporated.
