Short term and long term sigma

SpletThe difference between the Sigma Levels of a process over the short and long terms is called the Sigma Shift. Historically, people have assumed that the Sigma Shift is 1.5 and have therefore calculated long term capability by collecting only short term data, and subtracting 1.5 from the short term Sigma Level.
