I've the comments below from students who have taken Stat 566 recently. And thanks to the students who provided these comments via email, permitting me to include them here via cut and paste, without retyping. I learned a lot more about control charts than I thought I would.
Control charts are very powerful tools for learning more about the process.
The industrial statistics class I took as an undergraduate was taught by a graduate student. Naturally, the instructor did not have nearly as much experience in using control charts as Dr. Parr and, therefore, could not relay to us a lot of issues concerning statistical process control. I would have liked to learn about acceptance sampling. This was a really huge issue where I worked and I never got a good grasp of the correct way to sample. I would have liked less case studies about the X-bar and R chart.
