The key elements of a quality management system are a systematic approach to managing non-conformances and continuous improvement. The aim of this paper is to present quality improvement in a seat manufacturing company using statistical methods and quality control techniques. First, Pareto analysis was used to dentify the problem and reveal the critical causes in the management system. Following this, the 8D methodology was applied using a structured eight-step PDCA (Plan-Do-Check-Act) approach to problem solving. The paper presents the solution with respect to a rear seat manufacturing process where customer complaints and the need to rectify defects were identified in November 2021. Using the above methods, the root cause of the problem was identified, and permanent corrective actions were planned and implemented as recommended in the 8D report to reduce the likelihood of the problem recurring and increase customer satisfaction.
