Six Sigma is simply a method of efficiently solving a problem. Using Six Sigma reduces the amount of defective products manufactured or services provided, resulting in increased revenue and greater customer satisfaction.

Six Sigma identifies the cause(s) of your problem to efficiently develop effective solution(s).

Six Sigma originated at Motorola in 1986 and since then has saved organizations billions of dollars in virtually every industry.

What Exactly Does “Six Sigma” Mean?

Six Sigma is named after a statistical concept where a process only produces 3.4 defects per million opportunities (DPMO). Six Sigma can therefore be also thought of as a goal, where processes not only encounter less defects, but do so consistently (low variability).

Basically, Six Sigma reduces variation, so products or services can be delivered as expected reliably.
