My name is Emanuel, and I currently work as Production Engineer (the job profile is more supplier quality engineer). I have always worked in Quality, Product Quality, Quality Engineer, Customer Quality Engineer, Supplier Quality.
I my current assignment the RE (requirement engineer) recently defined CTQ (Critical to Quality) dimensions on drawing, but also marked as CTQ the thread of a screw for example, we are checking this by a GoNoGo gauge so we have ok/nok. Also tensile test is marked as CTQ but for this we only define min value ex. 3000N
The management wants to us to implement SPC for all CTQ, my question is how would you handle this attributive data in this situation? Any experience with this?
Any feedback is really appreciated.
Emanuel Alexandru Orzan, a good starting point is the Statistical Process Control Learn About Quality page: https://asq.org/quality-resources/statistical-process-control
Of most use to you may the additional references listed at the bottom of the page. I'd also encourage you to look at what is available in the Resources tab, especially the articles related to this topic.
I hope that this is helpful to you!
Thank you very much for your help.
