Abstract

Abstract. This study was aimed to identify cause of defect that occurred in new
products at automotive - spare part company by designing the right quality
management system with root cause analysis. Qualitative methodology was used,
where data and other information collected by interviews, direct observation,
document review, and evaluation of reports related to quality achievement. The
completion phase of this study was used the DMAIC concept as a corrective action and
continuous improvement for quality achievement. From analysis result, the factors that
cause defects in new products are differentiated by 11 defect categories. The
dominant defect category was ‘no taping option’ and TBO. The proposed quality
control design to reduce the number of defects are by adding more specific training
for new operators according to their own work, adding quality control process by
QC after the sub- assembling process, replace all opposite jigs with push pull jig
and adding verification tools and other production facilities by the QA-QC department
