It's also used in business. Six sigma is the holy grail of "close to perfection".

Interesting, haven’t heard about that. Can you give an example of how it’s used in business? What is actually measured?

[-] Rhaedas@kbin.social 2 points 2 years ago

I couldn't do better than Wikipedia.

Thanks. So I guess it doesn’t really measure anything in that field. Looks more like a strategy guideline and a set of techniques.

If you read the section on etymology of the business term, it was referring to the metric of quality control. Basically it means your QC is so good that a bad unit gets shipped only a tiny fraction of the time.

Processes that operate with "six sigma quality" over the short term are assumed to produce long-term defect levels below 3.4 defects per million opportunities (DPMO). The 3.4 dpmo is based on a "shift" of ± 1.5 sigma explained by Mikel Harry.
