Abstract : This communication takes support on research led within townships of size average. Our works make appear that the setting up of a territorial economic intelligence process (TEI) requires a particular methodology. For this reason we propose in this communication to make emerge a new gait that permits to optimize the setting up of a territorial economic intelligence device in a township. The modelling that we are going to unwind is at a time a production actionnable for managers that of new knowledge for scientists. It is about an operation continuum to achieve in a delay determined with means and objectives of quality. Is this carving in phases going to provide the methodology to follow by the territorial managers to install the device of TEI. This model of construction answer to their question "how to make this?".
