The added value of Planning Support Systems: A practitioner's perspective

Planning Support Systems (PSS) are geo-information based tools to support planning. Since the term PSS appeared for the first time in the late 1980s it has evolved into a serious academic subfield. In this debate, little systematic attention has been paid to the added value of PSS for planning practice. In particular the perspective of users requires more empirical attention. This paper attempts to fill this gap by answering the question: What is the practitioner's perception of the added value of PSS? In doing so we first develop a conceptual framework including the most important added values of PSS observed in the literature. Next, we describe an empirical study of the MapTable PSS, a support tool that is relatively frequently used in the Netherlands. Fifteen interviews were conducted and a Group Decision Room workshop was organized in order to systematically gather perceptions of users about the added value of this PSS. Added values that particularly emphasized are improved collaboration and communication among stakeholders, something which resonates with recent trends in planning. The added value of a better informed outcome is, somewhat surprisingly, considered less important. In order to deepen our understanding, we recommend more research in different contexts and with different tools. (C) 2014 Elsevier Ltd. All rights reserved.
