What is Six Sigma?

Six Sigma is defined as a type of business improvement methodology. Its main objective is to implement a vigorous process to systematically eliminate defects and inefficiency. It was originally developed by Motorola in the early 1980's and because of its proficiency has become extremely popular in many corporate and small business environments around the world.

Six Sigma's main purpose or objective is to deliver high performance, value and reliability to the customer. It is regarded and used around the world as one of the major themes for TQM (Total Quality Management).

Six Sigma was developed by Bill Smith at Motorola in the early 1980's. It was originally designed for a way to measure defects and to improve overall quality. A major position of Six Sigma is that by using the methodology, it can lower defects to a level of 3.4 DPMO (defects per million opportunities). 3.4 DPMO can also be written as plus or minus six sigma when the centerline spans 12 sigma positions. (Six Sigma comes from a technical term used in statistics)

While originally developed for quality control, Six Sigma is used in many different ways, such as improving communications with customers, employees and shareholders and improving the total process of interaction, communication and product design.

It should be noted that the term "Six Sigma" is a registered trademark, owned by Motorola. According to Motorola, this methodology has saved the company over 17 billion dollars from its inception to 2006.
