Studies of planning practice can be organized into a typology according to their substantive focus and research method. Case studies of planning situations and surveys of planners and planning agencies have been published for over twenty years. Further, studies appeared in the late 1960s and 1970s of how planning directors assess their roles and how public planning agencies work. However, interpretations of social interaction, organizational relationships, and political behavior represent a new way of exploring planning practice. This article notes that the findings of the studies reviewed could be made more accessible to practitioners and synthesized into theories of practice. Ltnda C.
