What is the defect rate of a six sigma process?
The overall defect rate, therefore, is 3.4 PPM. A similar argument applies to the extreme case of 1.5-sigma shift to the left. A Six Sigma process is actually 4.5 sigma in the long term, and the 3.4 PPM defect rate is the 1-sided probability of having a data value beyond 4.5 sigma measured from the short-term mean.
What does Lean Six Sigma mean in manufacturing?
Lean six sigma then is a methodology that looks to combine the best of both the lean manufacturing and the 6 Sigma approaches. In particular the emphasis is on obtaining the benefits of both methodologies, whilst minimizing any potential weaknesses.
