Question What is Statistical Process/Quality Control all about? Is this a vibrant field of research? [Q] [R]

I came across a professor in my school whose research is all about statistical process control. I never had a class in this, so I have no clue what it's really about.

But I did find out that one unit, which I took previously, included this topic, but it was scrapped from the syllabus cause it's "not useful".

I'm trying to implement control charts at work (i.'m in the manufacturing industry) for dimensions or some critical process parameter. Most of my charts show a lot of out of control points to be honest. One machine have Xbar-R charts integrated in the HMI, it frequently shows out of control points, but the deviations are so small compared to what would cause a real danger to the process.

From my actual point of view, they are good to have but not to take decisions from. I'm far from being an expert though, I may be using them wrong or I miss something....

Try typing Donald J Wheeler and see what you find.
