Errors In Six Sigma Process. The six sigma and lean manufacturing process can be very hard to understand for a lot of people. Six is nothing but an indicator, an acceptable error rate. For exemplification, the companies that operate on the Sigma level 1 perform correctly in a 30 percent proportion. The Sigma number grows as the performance ameliorates.
1 A z-score of .5 means there is a 30% probability of encountering a defect. 2  A z-score of .25 means there is a 40% probability of a defect.3  For a sample that is 6Ï, the probability of a defect is .0000001%. 4  Note: Values do not include a 1.5Ï shift.he further away a sample is from the spec limit the higher the z-score and process sigma. A higher process sigma means a less defective process. The term Six Sigma originates from the z-score.
