Chapter five, what is the difference between 99% quality and Six Sigma level of performance? In this chapter, you will learn what is the difference between 99% and Six Sigma level of performance. Six Sigma level of performance is also known as 99.9997% level of performance. You may see 99% quality is good enough for the customer, then why is there a need for driving Six Sigma low quality that is 99.9997% quality. Well, here's a snapshot of the difference between these two variables. At 99%.

More than 110,000 newborn babies are accidentally dropped by doctors and nurses each year. Whereas at six sigma, less than 38 newborn babies are accidentally dropped by doctors and nurses each year at 99%, no electricity for 85 hours each year. Whereas Six Sigma no electricity for only nine minutes in five years at 99%, no television transmission for nearly 64 minutes for V whereas, x Six Sigma no television transmission for 11 minutes in 10 years at 99% for short or long plane landings for the whereas, at Six Sigma one short or long landing every two years at 99% 16 Railway accidents per day whereas, at Six Sigma two railway accidents per year at 99% 16 minutes per week of unsafe water supply, whereas, x Six Sigma 1.4 minutes of unsafe water every five years well, now you know the reason why Six Sigma has been the most successful process improvement methodology since the 1980s.

Summary. In this chapter, you learned the difference between 99% and Six Sigma level of performance
