Defining Six Sigma (6
“Six Sigma: A comprehensive and flexible system
for achieving, sustaining and maximizing business
success. Six sigma is uniquely driven by a close
understanding of customer needs, disciplined use of
facts, data, and statistical analysis and diligent
attention to managing, improving, and reinventing
business processes.”
- Peter S. Pande6

Defining Six Sigma (6

• The Greek symbol
(sigma) refers to the
amount of variation in a process around the
mean value for that process
• Processes have acceptable upper and
lower limits
• Six Sigma is concerned with reducing the
variations to get more output within those
limits
)
Defining Six Sigma (6
• In the chart below, 64.6% of the measures are
between the upper and lower limits

• This is a 1 process
• Reducing the variations in the process will bring a
higher percentage within the acceptable limits

The 6
Difference
What is the Six Sigma difference ?
•
•
one typo per page (3 sigma)
vs.
one typo per library (6 sigma)
playing golf at a 6 sigma level means missing
one putt every 163 years
Brainstorming Exercise:
Where are the variations?
Identify six processes in your business that
have variations in the output.
(HINT: manufacturing, purchasing, inventory, forecasting,
product design, customer service, accounting...)
