Since the 2000s, several researchers from various disciplines recognize and question the information structure as the communication processes in territorial approaches. Catalyse method modelled some, whose specifications have been described over the publications of the INTI network (available on-http://halshs.archives ouvertes.fr/INTI/fr/) or disciplinary (see www.sfsic. org and http://rfsic.revues.org/). The structuring of information has seen technological developments described by other colleagues on INTI (JJ. Girardot, S. Damy, B. Hermann, P. Gerardin, G. Devillet...). The communication aspect necessary for this structuration must in turn be modelled and positioned in the overall vision of the Catalysis method. Many communicative spaces are necessary and form the backbone; individually, these processes can only be understood as a whole resituated (Catalysis method in action), where each process takes its meaning like an organ (which sometimes get sick) within a living organism. This holistic approach of the role of communication then enables to take the necessary distance to better understand this process, and to work to improve it.
