WebDec 9, 2024 · Six Sigma focuses on examining a process to find errors that are leading to defects in the product or service. The usual goal is to reduce variability and promote consistency. Consistent processes lead to a reduction in errors. That level of dependability is the goal of Six Sigma. WebA current six sigma process now will have an estimated shift of 1.5 sigma (lower) in the future and will perform at a 4.5 sigma level, which produces 3.4 DPMO.

A similar argument applies to the extreme case of 1.5-sigma shift to the left. A Six Sigma process is actually 4.5 sigma in the long term, and the 3.4 PPM defect rate is the 1-sided probability of having a data value beyond 4.5 sigma measured from the short-term mean. pipkin typeWeb4.C.3.
