The process of collaborative engineering design is relatively complex, and often results in various conflicts due to multi-actors interactions. Therefore, a critical element of collaborative design would be conflict situations resolution. In this paper, a process traceability based methodology is proposed to support conflict management. This methodology deals mainly with the conflict resolution team identification and the solution impact evaluation issues. A process metamodel is proposed in order to allow the design process traceability and the data dependencies network identification; which makes it possible to identify the conflict resolution actors as well as to evaluate the selected solution impact.
