What Is Six Sigma?

Wikipedia defines six sigma as: "a methodology to manage process variations that cause defects, defined as unacceptable deviation from the mean or target; and to systematically work towards managing variation to eliminate those defects"

It was originally created in the Motorola corporation in the mid 1980's, and due to the significant savings it demonstrably led to, quickly became adopted across a range of other organizations.

It comprises two methodologies:

- DMAIC (Define, Measure, Analyze, Improve, Control)

- DMADV (Define, Measure, Analyze, Design, Verify)

The basic method measures defects based around the statistical methods, the following being a common representation:
