Hi, Do anyone there have an experience to set organizational (plant) Cpk goals using Confidence Interval and/or hypothesis testing?
Most places use just point estimates for Cpk but in the liturature (like classic Montgomery SPC book) confidence interval approach is described. I'd like to hear about such Cpk assessment system, how does it work in practice.
