Is Six Sigma “zero defects”?
Six Sigma considers a mall, but finite, number of defects. The number is so small that it is perceived as “virtual perfection.” The fact that it is not zero (albeit small) allows people to “buy into” Six Sigma intellectually. Most people have a problem with “zero” because they are human and cannot believe in “zero.” They will, however, be willing to strive for only three parts per million because it is a finite number. They’re then willing to try for it, which is really all you need to get started.
