The evolution management of the business processes requires an exhaustive understanding of the change. An evolution engineer needs to understand reasons of a change, its application levels, and subsequently its impact on the whole system. In this thesis, we propose an approach for an a priori change impact analysis, to better control the business process evolution. This may help the business experts and the process designers to evaluate change impact in order to reduce the associated risks and estimate the related costs. It may also help to improve the service and quality of the business processes. This work contributes an eventual improvement, in regard, to verify the coherence and the compliance of the business process models, after each change. It leads to evaluate an a priori change impact analysis in structural and qualitatie aspects. The multiple-perspectives of the proposed approach have been reviewed experimentally. The validation of the approach is evaluated by exteding the Eclipse Development Environment, with the help of a set of plug-ins, as a prototype plate-form.
