brief introduction

Six Sigma is a nearly perfect quality management method based on data. Sigma is a Chinese transliteration of the Greek letter σ, which is statistically used to represent the standard deviation, that is, the degree of data dispersion. For continuous measurable quality characteristics: use "σ" to measure the deviation of quality characteristics from the target value as a whole. Several Sigmas are statistical measures of quality.

Any working procedure or technological process can be represented by several Sigmas. Six fit horses can be explained as 3.4 mistakes per million chances, that is, the pass rate is 99.99966%.

The passing rate of three eligible horses is only 93.32%. Six sigma management methods emphasize that all work is regarded as a process, and the factors affecting quality in the process are analyzed by quantitative methods to find out the most critical factors to improve them, so as to achieve higher customer satisfaction.
