Thanks for the explanation.
I wondered how two wait times with a similar loss could be considered so differently.
I assume Taguchi’s loss function also allows us to weigh the loss in terms of importance – unlike Six Sigma which considers all defects as ‘critical’ – even a slight delay.
I also tried to stay away from this argument ..
What you seem to be saying is a difference of a half a millisecond could separate a non-defect from a defect based on the customer’s KPI.
I thought Six Sigma subscribed to the Taguchi Loss function?
