the reseacher using the Six Sigma method with DMAIC’s phase (De ine, Measure, Analyze, Improve,
Control). There are many tools that the reseacher used, like project charter, SIPOC’s diagram, Voice
of customer (VOC), control chart, Fault Tree Analysis (FTA), Failure Mode Effect Analysis (FMEA).

complaints against BT products 8251 (42%) to (15%). Then the results of the control chart (u-chart)
that reject of the product sent to customer has not been controlled. After that, the causes were
analyzed using Fault Tree Analysis (FTA). Improvements are recommended to reduce defects based
on RPN (Risk Priority Number) from Failure Mode Effect Analysis (FMEA). There are several
suggestions that are tried to be applied in the industry but it still cannot be seen being followed up.
