The model allows us to analyze the quantitative and qualitative impacts of such a
change on all the processes. At the organizational level, internal restructuring are
quite frequent. The organizational models linked with the process models allows a
better management of the correspondence between the actors and the process.
4 Conclusion And Perspective
This paper focuses on how we can take into account the evolution perspective within
enterprise modelling. The first results discussed above, show a meta-model intended
to fulfill our requirements. The structure of this meta-model constitutes a first step
towards evolution management. However, as far as enterprise modelling is concerned,
additional modelling concepts are still to be formalized in the future, like evolution
events, process transformation, evolution scenario, or evolution processes…. Such
concepts will certainly be necessary to fulfill our goals [2].
Furthermore, such a meta-model provides only the first step towards evolution
management. The structure of the meta-model and the associated methodology are the
starting point that are used in order to develop further a decision aid approach for IS
evolution management. In this perspective, the meta model is currently used on a pilot
project in order to generate a chart of the enterprise (with all the necessary models)
focused on a limited pool of the firm’s processes. This data will be used to develop
two types of evolution management tools : (i) tools to define consistent processes
pools to be jointly managed within change scenarii ; (ii) tools to diagnose the impacts
and risks related to a selective change situation.
