The purpose of this paper is to control the propagation of non-conformities. The control methods implemented to ensure the quality performance of a production system present weaknesses, inherent to their constitution, which can let non-conformities propagate along the value stream. This propagation cannot be avoided, but it can be mastered. This paper presents a method to master non-conformities propagation in a production system by building the associated control chart. In order to calibrate the proposition, a case study on non-conformities propagation in a low-volumes industry in the energy field is presented. The simulation of the proposed plan shows the benefits of controlling this indicator.
