introduced by Motorola. It is a registered service and
trademark of Motorola, Inc. In 1986, Bill Smith designed the
specifics of the style. It started off as a set of procedures The Six Sigma symbol
designed to improve manufacturing processes and eliminate
defects. As of 2006, Motorola reported over US$17 billion in savings by putting Six Sigma into
practice.1
The name "Six Sigma" came from an array of statistics called process capability studies.
At first the reference was to the ability of manufacturing processes to produce a high
percentage of output that met specifications. The courses of action that function using "six
sigma quality" over the short term are believed to produce long-term defect levels that are
below 3.4 defects per million opportunities (DPMO). Six Sigma's inherent goal is to improve all
practices to meet that level of quality or higher.
The concept was triggered by six previous decades of quality improvement
methodologies like quality control, TQM, and Zero Defects. It was based on the works of
pioneers like Shewhart Deming, Juran, Ishikawa, Tagachi and others. Application of the concept
was then broadened to include other kinds of business processes as well. In Six Sigma a defect
