Folks,
Under a high volume production scenario, we can collect large sample size for process capability study weekly. Then we'd like to track the Cpk trend from week to week to see any special cause for Cpk value.
Does anyone have similar experience for this or it makes sense for that? The concerns from me is how can we get a UCL/LCL for Cpk. Same process as production characteristics? Customer requirement is Cpk higher than 1.33.
Thanks
