    Hi
        I would like to get Percentage of Error Rate for various Six Sigma Scale Rates(ie for Six Sigma 1,2,3,4,5 and 6).  One of my vendor specified that they are Six Sigma Rate 5.
     
    Thanks

    Ramesh,
     
    You can use iSixSigma’s “Sigma Calculator” to converst from error percentages to Sigma levels.

    or, the advanced mode (that allows you to deal in various ways with the very contentious issue of the “sigma shift”).

    Remember, this applies to processes, NOT companies or organzations.  If a vendor tells you that their COMPANY is a 5-sigma company, they are wrong.  If they tell you that they have some process that operates at the 5-sigma level, that means something (though, ask them to prove it, also).
     
    If you subscribe to the “1.5-sigma-shift”, then a 5-sigma process means it produces approximately 230 errors per million.
     
    Best regards,
