Abstract:
The Six Sigma methodology has been developed to identify, measure, analyse, optimize, and control process variation. It provides companies with a mentality focused on continuous improvement and a common language for efficiency. Nevertheless, there are still few scientific papers which present the methodology in practical case studies. By using the DMAIC model and a set of well-known quality tools, the present paper aims to exhibit a successful implementation of the methodology in the automotive industry, more specifically on improving the quality rate of a display production line. Thus, it proofs that small process improvements based on a solid methodology can drive competitiveness.
