ABSTRACT
This paper deals with the implementation of the QRQC method in a selected industrial enterprise, the subject of activity of which is the production of seats and their mechanisms, emission control technologies, and interior and exterior components for automotive. It is a quick response in quality management and its application is based on the Global 8D method. QRQC is also an effective and detailed problem-solving tool designed to prevent problems from recurring by introducing continuous improvement and changing the organization’s management approach. An analysis of NSF's assembly division, where they deal with the assembly of dashboards, found that the scrap rate is €390 per day. Elimination of the non-conforming pieces took place on the assembly line where the painted parts are assembled into the dashboard. The role of the QRQC is not to find out why paint defects occur at an in-house paint shop supplier, but to find out why operators do not identify paint defects before the painted part is assembled and welded with other parts. The company has been tracking the development of non-conforming parts based on the Stop Scrap project, which implemented the QRQC method, and the scrappiest part turned out to be the left-side dashboard welded to the painted pad, with paint defects on the painted pads being the most common defect. As a final step, the effectiveness was evaluated after the implementation of the measures proposed in the QRQC. The importance of the study is that the current economic situation is critical for many industrial organizations and cost reduction is key to long-term sustainability The consequence of using the QRQC method is a reduction in the number of non-conforming parts by almost 50% after almost 6 months.
