In the past, the connector industry applied traditional thinking to indiscriminate reducing the manufacturing costs for improving profit margins, while ignoring the Cost of Poor Quality and other indirect manufacturing coasts. This is a practical case. The root cause which causes to high Cost of Poor Quality is in poor process parameter settings. The reason resulted in unstable product quality as well. When mass production, there are many of abnormality were produced in the client side. So that, high Cost of Poor Quality was rose and profit margin was affected as well. The study through the DMAIC approach of Six Sigma that it was applied in the electronic industry currently to find out the factors which impact Cost of Poor Quality of connector manufacturing. BTW, it applied the Taguchi methodology to find the best levels of control factors and improve Cost of Poor Quality and increase profit margin. In this case, the Six Sigma team applied successfully DMAIC approach in controlling effectively the factors which cause to poor quality and yield rate was enhanced to 98.52%, this way helped company in the case study to save ten millions of Cost of Poor Quality.
