ABSTRACT
This chapter presents the Plan-Process-Results (PPR) methodology and proposes PPR as a methodology to evaluate planning and plan implementation. It describes its theoretical background and its main methodological aspects and also describes the application of PPR to the Plano Director Municipal (PDM) for Porto. This evaluation exercise was developed in an academic context in 2006 in the beginning of plan implementation. The chapter explores the use of PPR as a planning framework and methodology. It draws on an exercise developed together with planning practitioners in the Porto local authority in the middle of the PDM implementation. The design of PPR was framed by seven principles to structure and guide the evaluation process in urban planning established after a comprehensive literature review covering a wide range of topics, namely the evolution of evaluation theory and methods, the contemporary debate on planning evaluation, and the practice of planning evaluation.
