However, when an engineer’s meeting that involved in the production line by used the cause and effect diagram for analysis was found 2 main causes be the lack of staff’s skill and improper practices. Solutions for improvement a problem are redesign and improve the working method including new standards for inspection.
A result from the solutions was found the proportion of defect is decrease from the data collected in July and August 2558 was found defects amount of 722 pieces and 455 pieces respectively.
