PSS design: a general framework perspective

The paper presents a tentative framework for Planning Support System (PSS) design. The aim is to aid planners to fully exploit the potential offered by the introduction of Spatial Information Technology into planning practice. The framework proposed is based on a taxonomy of PSSs, which
offers different conceptual models useful to adapt a general PSS model to different planning processes. The taxonomy is intended to set the application domain on which planners and developers may enhance the dialogue in system requirements analysis. A case study is proposed to illustrate the framework
application and a perspective for further research development is given.
