ABSTRACT
Planning evaluation has been an established field of research for a considerable number of years. Its development had been closely associated with changes in planning theory and practice as well as in policy analysis and programme evaluation. Planning evaluation most obviously refers to the making of normative judgements about the success (or otherwise) of the intervention outcomes of planning or assessing the success of the process of planning. As such, planning evaluation acquires knowledge from a vast number of disciplinary sources. It is difficult to track down all the changes that have taken place in the field of planning evaluation during these years. Very roughly, however, we can discern the development of planning evaluation research along three lines: the fundamentals and purpose of planning evaluation, the scope of planning evaluation, and the methodological innovations and improvements.
