To achieve Six Sigma quality,
a process must produce no more than 3.4 defects per million opportunities.
An "opportunity" is defined as a chance for nonconformance,
or not meeting the required specifications. This means we need
to be nearly flawless in executing our key processes. Six Sigma
is a vision we strive toward and a philosophy that is part of
our business culture.

Our Customers Feel the Variance,
Not the Mean
Often, our inside-out view of
the business is based on average or mean-based measures of our
recent past. Customers don't judge us on averages, they feel
the variance in each transaction, each product we ship. Six Sigma
focuses first on reducing process variation and then on improving
the process capability.
Customers value consistent, predictable
business processes that deliver world-class levels of quality.
This is what Six Sigma strives to produce.
