The choice of the actors who are assigned to a project is crucial for the project as it involves a nonnegligible part of its future performance. Risk analysis mainly focuses on risks which may occur during the execution process and not during this important actor choice process. We argue that it is possible to improve this classical analysis by two additional ways. First, our work identifies the main types of risks which may occur during the decision-making process, focused on actor choice. Second, we analyse the potential propagation of a wrong actor choice and its global consequences. We are then able to correct the estimated value of the risk by considering its position as a node in the complex project network. The results obtained through this research are promising in terms of identification of new risks and in terms of reestimation of some risks. This methodology has been applied in two industrial situations: Vallourec Group and Peugeot-Citroën.
