A framework to re-organize design activities during engineering change process

International audienceDesign has increasingly become a collaborative endeavour carried out by multiple actors with diverse kinds of expertise. Due to the multi-actors interaction conflicts emerge during the design progress. Hence, a critical element of collaborative design is to manage conflict and particularly the impacts once they are resolved. Indeed, the conflict resolution comes up with a solution which often implies modifications on the product and the process organisation. This paper deals with this problematic of changes impact on conflict management process. It quantifies key issues with regards to concurrent engineering that enables us to better manage the design process. Strategies to overlap coupled activities are proposed based on the dependencies between the handled data during the design process. Furthermore, a framework to optimise re-organising design activities is proposed
