SIX SIGMAWhat is Six Sigma Six Sigma is method for achieving continuous quality improvement in all production processes. You won’t find any vague notions or half-baked theories here; Six Sigma is a structured way of substantiating and solving problems with facts and hard figures. Six Sigma is designed to reduce variation, which makes processes manageable and predictable.
Six Sigma can be traced back to Carl Friedrick Gauss (1777-1855) who introduced the concept of normal division. However, it wasn’t until the 1980s when Motorola realized that their level of Sigma is the letter in the Greek alphabet used to pinpoint shortcomings and deviations in production processes. Reducing the number of shortcomings increases the quality of the work. This applies not only to production but also to all other activities, such as purchasing, logistics and financial administration. |

quality was no longer up to the mark and they went to work using Gauss’s theories. The company wanted to shift from measuring defects per thousand to measuring defects per million. By combining known tools and statistics techniques into a single program, Motorola developed the method that we know today as 6σ (Six Sigma). Six Sigma delivered Motorola huge quantifiable improvement results in the billions. Many companies around the world later implemented Six Sigma.
