THE GENESIS AND HISTORY OF SIX SIGMA
The roots of Six Sigma as a measurement standard can be traced back to Carl Frederick Gauss (1777-1855) who introduced the concept of the normal curve. Six Sigma as a measurement standard in product variation can be traced back to the 1920's when Walter Shewhart showed that three sigma from the mean is the point where a process requires correction.
Since the 1920's mathematicians and engineers have used the word ‘sigma’ as a symbol for a unit of measurement in product quality variation. In the mid-1980's engineers in Motorola Inc in the USA used 'Six Sigma' as an informal name for an in-house initiative for reducing defects in production processes, because it represented a suitably high level of quality In the late-1980's following the success of the above initiative, Motorola extended the Six Sigma methods to its critical business processes, and significantly Six Sigma became a formalized in-house 'branded' name for a performance improvement methodology, i.e., beyond purely 'defect reduction', in Motorola Inc.
In the early and mid-1980s with Chairman Bob Galvin at the helm, Motorola engineers decided that the traditional quality levels -- measuring defects in thousands of opportunities -- didn't provide enough granularity. Instead, they wanted to measure the defects per million opportunities.
Motorola developed this new standard and created the methodology and needed cultural change associated with it. Six Sigma helped Motorola realize powerful bottom-line results in their organization - in fact; they documented more than $16 Billion in savings as a result of our Six Sigma efforts.
Since then, hundreds of companies around the world have adopted Six Sigma as a way of doing business.
