Due to demand of overlap tire is the main portion, around 58% compare with others. Recording to TBM overlap performance tracking from January to December Y22, Productivity Target average is 224 but the Actual is 185, which less than target around 17.4%. In Q1 Y23 Productivity Target average is 209 but Actual is 173, which less than the target 17.1%. We start to see the bad signal. Even if machine capacity can support the demand, but we also loss performance to support these activities. Therefore, we decide to do this project to eliminate unnecessary waste from the process by using lean approach to respond customer needs and company benefits.
