I am a planning consultant for a Norwegian firm and currently working on a project where I need a brief overview of the development of different theoretical approaches to planning (strategic planning, rational planning etc.). This is perhaps embarrassing since I am an urban planner myself, but I cannot find an adequate and UPDATED overview and I do not have time to read x books.
I hope that anybody can direct me to a recent article etc. (I think I saw one in the APA Journal a few years back, but I cannot find it). All help will be highly appreciated.
