Hi everyone, last time our company had IATF audit, auditor request UCL and LCL must be show Xbar-R, but at current month not complete so we can not calculate UCL and LCL of this month and update on Xbar-R sheet then he suggest use data last month get UCL & LCL then draw on next month sheet. is this right? How about your site control this. This thing there no regulation for require it.
Thankyou
