The quality of the product is without any doubt a condition of competitiveness. But to perpetuate the manufacturing system, one needs define in a coherent way what the quality of a product implies for the whole manufacturing system and what the actions to be launched are, in order to improve quality without endangering the system. Actually, a whole bunch of tools is proposed to companies to help them deal with their quality problems. They are efficient forspecific problems but do not allow that managers map the whole system. However, this mapping is absolutely necessary to lead the quality system to being a helping tool for the manufacturing system in achieving its objectives by respecting the strategic, tactical and operational decisions without disregarding the triplet (quality, cost, delay). In this paper we will present the state-of-the-art of various ways and tools dealing with quality. We will also present the concepts developed at the GRAI/LAP in order to model the quality system and to integrate it with operational manufacturing
