History of Lean Six Sigma

Back in the 1920’s, Walter Shewhart showed that if there was a three sigma from the mean of a particular point in the process, it required correction. This measurement was then coined “Six Sigma” by Bill Smith who worked for Motorola as an engineer. These people got the information from Carl Federick Gauss who developed the Gauss’s law still used in physics today. Back in the 1850’s introduced the concept of a normal curve. Six Sigma is a standard measurement in product variation.

Bill Smith, while working with Motorola, developed a new standard and created the procedure and needed update to the outdated standards that were currently being used. Since then, countries around the world use this method when doing business.

Over the years many businesses have utilized the Six Sigma process to streamline their production. Some examples are The Ford Motor Company, Toyota, and John Deere all have seen improvements with the Six Sigma process.
