Hi,
My current processs in in statistical control but it's not capable of meeting the specification of 0.63 +0.02 -0.03. My process has done everything to improve and this is the best they can achieve. My question is can I still use control chart to control my process to reduce the scrap level? How shall I establish my control limits so that I can input it in Minitab under the S limits for Upper & Lower bound?
I have done control charts on the 4 IDs and the control limits are covering my spec. limits.
Please help.
