The reduction of defects, cycle-time, cost

The sigma scale of m

9、easure is perfectly correlated to such characteristics as defects-per-unit, parts per million defective (PPM), and a probability of a failure/error. The sigma value indicates how often defects are likely to occur. The higher the sigma value, the less likely a process will produce defects. As sigma i
