Replying to LO29862 --

I might be under a misapprehension, however I believe the term Six Sigma
is a reference to the normal distribution of data, and the 'fact' that
99.5% of values in a normal distribution lie within plus or minus three
standard deviations of the mean. Is this correct? I believe 'Six Sigma'
system refers to Statistical Process Control, am I showing my ignorance?

Best Regards,
Alan Cotterell
