The paper presents how to select modules of an information system, applying a multicriteria decision approach, using the interactive multicriteria decision making method - TODIM. The problem is to assign priorities for information modules in the planning stage of information systems. These priorities should be attributed in agreement with the decision makers’ preferences, considering the impact on strategic factors and operational aspects of processes, as examples of criteria. The TODIM method is based on the prospect theory and has the technical resources to minimise the possibility of occurrence of the reversion order. It also allows the multicriteria decision approach a group of interdependent actions; this method uses the additive difference model to determine the ranking of an alternative over another one. An analytical structure is proposed to incorporate the multicriteria TODIM method, integrated with the information system planning methodology. Strategic factors and operational aspects of processes are integrated.
