Approximate Sigma capability for process
Hi to all, Theorectically, to calculate the sigma level of a process, one has to divide a known decetive rate by the number of CTQ to obtain DPMO,

How is the defects per million opportunities (DPMO) to Sigma level and yield conversion chart
We must understand the “Sigma” of a process is merely an equivalent unilateral figure-of-merit. As such, it is always regarded (and reported) as a
