There is no point in listing an equation if you are not going to define what the variables mean. Namely, what on earth is do USL and LSL stand for? Even sigma should be defined for those who do not know what they are looking at.

... and how are these interpreted?

It would be really helpful, I think, if someone could add a sentence or two for each measure to say what a "good" value is ... e.g., 1.0 is good, higher is better, things like that. Sn14534 13:13, 19 July 2007 (UTC)[reply]
