What is Six Sigma?
Six Sigma is a disciplined process which,
by using data,
systematically reduces defects.
The next several slides are a brief introduction to Six Sigma and to the video.
Instructor Note:
The following slides have been hidden to shorten the introduction
Champion slides 12 to 16
BB slides 19 to 22
Process Overview slide 52
These slides may be used at the discretion of the instructor.

3. What is Six Sigma?
Six Sigma is about stopping defects before they happen.
Changes focus from fixing products to fixing processes so they make excellent products.
Reduces defects most important to the customer

4. Success Tree of Six Sigma
6 s Continuous Improvement Success
Sweet Fruit
5 s Wall, Improve Designs
Bulk of Fruit
4 s Wall, Improve Processes
Low Hanging Fruit
The 3.5/4 sigma wall is caused by lack of measurement systems, hypothesis testing, and DOE usage.
The 5 sigma wall is a result of processes that were not designed from the start as 6 Sigma processes. (need DFSS – design for six sigma)
3 s Wall, Beat Up Suppliers
Ground Fruit
