2 Six Sigma is a disciplined process which, by using data, 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 introductionChampion slides 12 to 16BB slides 19 to 22Process Overview slide 52These 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
