* Our goal for Six Sigma is to reduce variation in our process as well as center our process. This will result in fewer defects. From the customer’s point of view, variation has more of an impact on them rather than the mean. This can be explained by the following: If your process for delivering orders has high variation, ranging from 5 days to 45 days, with a target of 20 days, then your customer may receive an order any time in this range. Five deliveries received by the customer may be 7, 34, 12, 27, and 39 days. The average would then be 23.8 days. You may perceive that the customer, on average, is receiving his orders close to your target of 20 days. However, they “feel” the late orders of 34 and 39 days. Take Away: Reduce Variation and Center Process. * TELL: ASK: DO: * 1 TELL: The page is “dog eared.” This is a cheat sheet to help you track/monitor your DMAIC project. Note the 5 phases of the project, 3 steps in Define, and the 12 steps in MAIC, and the key deliverables in each phase. ASK: DO: Update the page in slide show * TELL: Start with what DMAIC does and how DFSS builds on it. Briefly highlight the DFSS methodology – talk about DMADOV, the table; mention that every aspect of the table will be covered in more details during the DFSS training week. Highlight Steps 8, 9 and 10 forms the core of DFSS. Key Takeaway: Stress not to de-couple DMAIC from DMADOV even for new designs.
