摘要：
It was in 1999 when LG Chemical's PVC production facilities adopted the Six Sigma Initiatives. Although we had never applied Six Sigma methodology in our PVC production lines, it did improve PVC quality. Defining quality from a customer's viewpoint and applying statistical analysis to identify the factors that influence quality, allowed us to improve chronic quality problems, such as unfused particles on the PVC sheet surface (hereafter Fish-eye). We improved the quality level from 0.72 to 5.3 sigma and above after using Six Sigma tools.
