Rational Versus Communicative: Towards an Understanding of Spatial Planning Methods in German Planning Practice

This paper considers the use of planning methods in German planning practice against the background of the ‘communicative turn’. The debate about concepts of rationality in Germany as well as in other countries can be said to have resulted in the paradigm of communicative actor-oriented planning achieving at least the same standing as the analytical rationality of the classical expert-based planning model. The inconsistent use of the term method in research corresponds to empirical findings indicating that the term is used ambiguously in practice. Nonetheless, planning methods fulfil a number of functions in practice. The notion of a relatively clear division between ‘analytical-rational’ methods on the one hand and ‘communicative’ methods on the other hand was relativized by experimental investigations. The setting in which the methods are applied seems of more importance; even apparently ‘analytical-rational’ planning methods can be implemented in a more or less communicative fashion.
