Information systems have to be continuously updated due to changing requirements in the work environments of the enterprises. Enterprises are also changing their way of working towards networked organisations which demands a higher flexibility in the integration with different partners. Legacy systems represent valuable investments and information resources to take care of. Therefore there exists a demand to improve possibilities for changing and integrating software applications within and between enterprises. The intention with this paper is to penetrate the research that is being done in order to facilitate integration of software applications within and between enterprises. This involves enterprise modelling as well as software modelling.

Future work will concentrate on how to enable integration of software applications in the extended enterprise with changing needs, using enterprise modelling.
