A small group at the School of Social studies in Brno and Proverbs Inc. Prague, Czech republic, worked on a composition of a model, which is to test communication policies. The City hall faces problems in communication and explaining some of its long-range goals. The model is derived from the J.W. Forrester’s model of urban growth and includes also some „soft“ variables, which seriously effect the perceived leadership role of the City hall and its ability to proceed further and to gain public support. The paper discloses the structure of the model as well as the process of its construction and obstacles, which the group encountered while attempting to offer its expert service.
