Six Sigma history can trace its roots back to the statistical measurement of standard introduced by a man named Carl Frederick Gauss. Carl Gauss introduced the concept of what is popularly known in the statistical world the concept of the normal curve. Six Sigma works as a measurement standard in many production variations since the 1902s, when a man names Walter Shewhart demonstrated that three sigmas from the mean is the part where a certain process will require the necessary corrections. A lot of measurement standards came soon after, but we can credit a man named Bill Smith for the term six sigma.
Motorola was the company where this Bill Smith worked, and in the early and mid 1980s he and other executives measured their companys defects against a million opportunities to provide enough granularity. Motorola is responsible for developing this new standard and also created the exact methodology of six sigma. Through this creation, Six Sigma was able to help Motorola realize powerful results in their company, enough to be able to document more than an astonishing sixteen billion dollars in savings all thanks to their six sigma efforts. Since that time, hundreds of companies the world over began clamoring for the use of six sigma in their respective businesses. This was made possible by many direct praises given by many leaders who were extremely enthusiastic about the benefits of using six sigma, such as the leaders of established companies like Honeywell (formerly called Allied Signal) and General Electric Company.
