Using organizational analysis and IDEF0 for enterprise modelling in SMEs

This paper deals with enterprise modelling, and pays special attention towards the requirements of Small and Medium Enterprises (SMEs). Among existing methodologies, SADT/ IDEF0 is examined and chosen as a starting point. After having discussed some of the problems connected to the use of such methodology, a new approach is proposed. This method maybe seen as a bottom-up variant of SADT, which allows us to reduce the model development time, decrease the influence of subjective viewpoints during the modelling process, and increase the ease with which information in the model maybe subsequently processed. Finally, the application of the proposed methodology in a medium-sized enterprise is briefly reported.
