Six Sigma is a business management strategy that seeks to improve the quality of process outputs by identifying and removing the causes of defects (errors) and minimizing vari…ability in the business and manufacturing processes. Six sigma uses a set of quality management methods and creates a special infrastructure of people within the organization. A sigma rating indicates yield, or the percentage of defect-free products it creates. A six-sigma process is one in which 99.99966% of the products manufactured are free of defects. Six Sigma has been used by multinationals (MNCs) with great results. While statistics has a role in Six Sigma, its emphasis has been blown out of proportion. Six Sigma is a methodology that provides businesses with the tools to improve the capability of their business processes. Six sigma helps to solve most business problems with improved process knowledge. This increase in performance and decrease in process variation leads to defect reduction and vast improvement in profits, employee morale and quality of product. Six sigma certification is of three types - yellow, green and black belt. There are many organizations and institutes that offer certification. However, currently there is no central certification body, neither in the United States nor anywhere else in the world. (MORE)

If I understood correctly, you are asking about calculating sigma in MS Excel.
If A2 is cell has defects and B2 has total number of opportunities. Then copy-paste this formul…a in C2 cell.
=IF(A2=0,6,IF(A2=B2,0,IF(B2=0, "DENOMINATOR CANNOT BE ZERO",ROUND((NORMSINV(1-A2/B2)+1.5),2)))) (MORE)

sigma represents standard deviation. In a normal distribution, +/- 1 sigma from the mean, for instance, corresponds to approximately 67% of the area under the normal distribut…ion. +/- 2 sigma corrresponds to 95% of the area and +/- 3 sigma from the mean corresponds to 99% of the area under a normal distribution. The area that is covered under +/- six sigma from the mean corresponds to nearly 100% -- that is, the part of the area NOT under that +/- 6 sigma is in the 10^-15 range or 1/1,000,000,000,000,000. The six sigma name borrows from this to suggest that the method gives this degree of certainty: that in 999,999,999,999,999 in 1,000,000,000,000,000 cases the result will be predictable. It does nothing, however, to explain how an agricultural process management methodology applies to other fields. (MORE)

its a statistical term for standard diviation. in normal distribution if there are six standard deviations between the process mean and the nearest specification limit, the…n there is a 99.99966% probability that no items will fail to meet specifications . In six sigma 1.5 sigma correction is considered to allow the natural variation present in any process. So when we say that process is sis sigma , it is nactually 4.5 sigma. (MORE)
