摘要：Six Sigma is the most efficient existing method for solving the commercial logistics problems made available to companies. Initially, this was a set of practices that were used in the manufacturing processes for removing the defects, but over time, the concept was extended also to other types of activities. In 1986, Bill Smith from Motorola developed the specific Six Sigma elements for the first time and stated that level 6 Sigma corresponds to an output of 99.9997%, meaning 3.4 defects/million opportunities in the commercial logistics activity.
