ABSTRACT
Keeping stability of operation or product quality is a required competency for quality control in manufacturing industry. For controlling the products quality, the relevant data must be measured and inspected to judge if the quality of products confonns to the specifications. Originally, the accuracy of the measured data varies from each other among different operators. Therefore, in this study the causes of measurement deviations among different operators were analyzed from ergonomics point of view. Improvements were proposed and implemented.
