    Dear All,

    I have calculated the DPMO of an exercise and now, I would like to know how to calculate the Sigma level, if possible.

    The values I have are:

    Defects: 120000
    Opportunities (Units): 1500000
    Defect Opportunities per unit: 10

    DPMO: 8000

    Based on the result, I would roughly say that the Sigma level would be between 3 and 4 but how can I know the exact level?

    I will appreciate if you could support me with some ideas?

    Many thanks,
    William

    C’mon now! Since you know DPMO just look it up in the table. Or use the calculator at this site.

    I have found the formula that could be used on excel in order to calculate the exact Sigma level and wanted to share this with you all.

    =ABS(NORMSINV(DPMO/1000000))+1.5
