It brings to the system how the quality control should be done in order to assure the product quality and the customer’s satisfaction. Nowadays the production systems have to continue to improve its performance in order to be more competitive and the quality plan has to follow this trend too. In this work we will present a case study developed in Saint-Gobain Mondego, SA, whose goal was to improve the quality plan in order to reduce the product non conformities and simultaneously the costs associated with the quality. The present work makes firstly a presentation of the enterprise production process and an overview of how the quality controls it is performed during the process. After that, we will characterize the problem that Saint-Gobain proposes to study; our propose to decrease the problem; the tests effectuated and the analysis of the results; and the final conclusions about this case. How we will see, there are strong signs that the proposal tested will bring quality improvement associated with a cost reduction and consequently better satisfaction for the customer.engQuality improvementQuality planQuality costs reductionCustomer satisfactionContinuous improvementjournal article10.26537/recipp-23055
