increasing quality to levels that consistently meet
or exceed customer expectations. The name "Six Sigma" derives from the
statistical term for a level of standard deviation of no more than 3.4
defects per million opportunities (DPMO);
a quality level of no more than 3.4 DPMO is the objective of businesses that
use Six Sigma methodology. |
