1. Explain Six Sigma Simply (Football story from SSDSI) http://www.sixsigmadsi.com/ Six Sigma Simplicity

2. Reduce Variation, Make Money We teach the concept of ‘Six Sigma’ with a story that helps our students understand the concept. A football coach is evaluating five kickers as field goal kickers for an upcoming game. He has a GPS solution that tells him exactly where the ball crosses the field goal. He gives each of his kickers 100 chances to kick the ball through the goal posts (spec limits) from the center of the field at 35 yards back. His first four kickers take their turns. Each kicker kicks all 100 balls between the uprights, but all four kickers were "all over the place", meaning that they never consistently crossed the goal post at the same point. The fifth kicker also kicks all 100 through the uprights but he consistently "splits" the uprights. We then ask the class, "Who are you going to choose when it comes time to kick a field goal during the game?". Most will choose the fifth kicker. Why?... because he is more consistent. The fifth kicker will be more predictable because he has learned to have better control over the critical inputs when kicking the ball. If you were to film all 100 kicks that the fifth kicker made, you would see little variation in his kicking method which leads to little variation in his output, which is the ball "splitting the uprights“ down the middle.

3. Sigma Illustrated Sigma is used to describe the “spread” of a distribution relative to it’s center (mean) What changed in the graphs below? Six Sigma Simplicity

4. How Does Sigma Help? Most things in nature to have a common shape relative to variation That common shape is referred to as a normal distribution Using that normal distribution allows us to determine a probability of occurrence based on some middle value and the amount of variation in the group Six Sigma Simplicity

5. Normal Distribution The area under sections of the curve can be used to estimate the cumulative probability of a certain “event” occurring 43210-1-2-3-4 40% 30% 20% 10% 0% 95% Probability of sample value Number of (sigma) standard deviations from the mean 99.73% 68% Cumulative probability of obtaining a value between two values Six Sigma Simplicity

13. Business Impacts of Variability Prevention Costs – Education and training – Safety – Controlling processes Appraisal Costs – Incoming inspection – Maintenance and calibration of equipment – Process audits Internal Failure – Incorrect transactions – Things Done Wrong – Rework – Re-inspection – Late Delivery Times External Failures – Processing customer inquiries – Incurring penalties/claims – Lost sales Six Sigma Simplicity

14. Lean + Six Sigma Work Together Along with the Kaizen (waste reduction) process, the concept of ‘Six Sigma’ is another structured team approach for improving process performance It emphasizes the importance of identifying key critical inputs that effect your key outputs through statistical analysis It drives for perfection in those processes by reducing variation and/or moving the mean Six Sigma Simplicity
