A decision modelling approach has been proposed to select modules of an information system (IS). This approach can be applied in a planning stage or in a management basis. The decision maker's preference indicates priorities. Preferences are modelled through PROMETHEE method, which deals with criteria such as: impact on strategic factors and operational aspects of processes. The paper includes the methodology and a case study with numerical results.
