I was talking with my one of my coworkers from the technology field about Six Sigma and 3.4DPMO. He was excited about Six Sigma and how it has a revolutionary impact in the quality field. He followed the concept very well and was happy that he now knew why Six Sigma was so popular.
However, he observed that Six Sigma focused on the number of defects. According to him, this was a negative focus...where the Six Sigma method focuses on the number of quality problems found.
My technology coworker thought it would be nice to change the focus on the positive.
For example at Six Sigma, in a million parts produced, 999996.6 parts are good.
This was an interesting way of looking at Six Sigma and changing focus to the positive side.
Do you know why Six Sigma focuses on defects per million opportunities?
