Calculating Sigma Level

Recommended Posts

Hello,

I would like to know that if there are no defects in units used for samples, how could we calculate sigma level for that product?

For example

In a process 10000 files completed in 3 months and there are no errors in this duration in any of the file. Now I have to calculate the sigma level of this process for 3 months, what method I should use?

Please help me.

Thank you

Hi Arik,

Sigma level cannot be calculated in this situation. This is the disadvantage of discrete data. Unless you get defects/defectives, you cannot assess the z value.

I think one may go for Continuous data instead of Discrete data in these cases.

Continuous data can assume a range of numerical responses on a scale and it can be used to measure a wide range of different values which will lead to even the slightest defect being detected and measured.

Can someone please suggest, if this can be the correct approach?
