Abstract
Minor defect is a defect category that made to anticipate the types of potential defect. These preventive actions generate the increasing type and number of defect (there are more than 34 types of defect for minor defect and will continue to grow). Therefore, it’s required a number of efforts to reduce the number of defect and to eliminate the types of defect. MEDIC method is used to reduce the number of defect with high frequency of occurrence. We get 17 types of defect to be done, and then we identify the root causes that result 51 proposed solutions. From 51 solutions, 10 of them are implemented. As the result, the defect proportion of 11 from 17 defects are significantly reduced with α=5%. The Deming Cycle (PDSA) method is used to eliminate the types of the defect with low frequency of occurrence from defect list. We get 14 types of defect to be eliminated. And then, for the trial period (11 days), we get 13 from 14 types of defect that will be proposed to be eliminated, because they have not emerged for the last 3 months and have passed the trial period.
