Is there any sigma beyond six sigma?
In theory, there are infinite sigmas beyond six sigma. In reality, the cost and ability to move from six to seven sigma in a business process is usually not worth the return. At a six sigma quality level, you would expect 3.4 defects per million. At seven sigma quality, you would have 0.007 defects per million. There are some processes that may run at seven sigma quality, but six sigma is a better goal which the vast majorities of businesses will never manage to reach.
What is 12 sigma?
12 sigma is actually 1.8 defects per 10^33 opportunities or if you subscribe to the bogus notion of the 1.5 sigma shift, it would be 4.3 defects per 10^26 opportunities. It is nonsense to talk about such things as no one would know how to measure or achieve such performance. The notion is only good for discussions when pontificating one's naval. 1.5 defects per million opportunities is the answer for 12 sigma. Its primarily used in the aviation industry.
Six sigma certification?
Six Sigma is a business process that is designed to improve the effectiveness of business processes by reducing the number of defects that appear in products or services.

A six sigma rating indicates that there are only 3.4 defects per million of the business' product, meaning that the products are 99.9% defect-free.
