Six Sigma’s “Sigma” section refers to knowledge evaluation. Six Sigma analyzes product manufacturing and supply information to identify common deviations. These are deviations from the mean or closest limits of customer specifications. The goal is to reduce errors and defects to a maximum level 3.4 per 1,000 capabilities. Six Sigma-adopted companies may have better customer support, reduced cycle time, better compliance with laws, standardization of enterprise growth, and improved customer service. Six Sigma trials are not easy to implement. All employees may need to be on board for months or even years. They should also be able to follow the procedures and retain the benefits and values.
