Abstract (EN)

The aim of research is to test the model of interaction space as a tool to support the plan conception, in the context of a public decision process.Interaction space model allows to analyze the interaction mechanisms that a public process generally activates, and help the planner, or more generally the analyst, to understand what kind of development the process could have, in order to address its progress.The model has been tested during the planning process in Laurenzana, small village in the South of Italy. The paper describes the implementation and carries out some criticisms related to the not well structured relation between the space interaction model and the public decision process: once the interaction space is completely developed, the public process is generally at the beginning of implementation phase.
