After you’re done reading this blog post, you will be more familiar with these four Six Sigma tools — defects per unit (DPU), defects per million opportunities (DPMO), parts per million defective (PPM), and rolled throughput yield (RTY). You’ll know how they work and how to calculat...
DPMO:defects per million opportunities % defects:percent of total opportunities that were defective % yield:percent that is not defective (1-% defects) Sigma:sigma level associated the the calculated DPMO (see reference table in columns D1:E9.) Zst:Z short term DPMU:defects per million units ...
Six Sigma is a disciplined, data-driven approach and method for eliminating defects. The term itself is derived from statistics, whereby one tracks "defects per million opportunities." In this case, a "defect" is described as anything outside of customer expectations. Six sigma project ideas ...

1 Sigma:A process with very poor quality, with approximately 690,000 defects per million opportunities (DPMO). 2 Sigma:Still poor quality, with about 308,000 DPMO. 3 Sigma:Moderate quality, about 66,800 DPMO, which translates to 93.32% yield. ...
To achieve Six Sigma quality at GE, a process must produce no more than 3.4 defects per million “opportunities”. An opportunity is defined as “a chance for non-conformance, or not meeting the required specifications”. The company says: “Six Sigma has changed the DNA of GE. It is now...
The SigmaLevel is a statistical calculation. Ittakes short-term information regarding thedefects per million opportunities(DPMO) of a process. Further, it factors in the inclination of a process to shiftand gives a level score representing the modified DPMO. It uses thisshift to determine if the...

Six Sigma is based on the idea that all business processes can be measured and optimized. The term Six Sigma originated in manufacturing as a means of quality control. Six Sigma quality is achieved when long-term defect levels are below 3.4 defects per million opportunities (DPMO). ...
