What's the difference between QA and QC in chemical plants and pharmaceutical plants? Please describe it briefly, don't copy and paste those theoretical things.

I am QC, and you are right. QC is the quality inspector QA sitting in the office, but I am not in charge of QC inspector. My responsibilities are different, and QA is also very troublesome. Face documents, SOPs, open lists and so on every day. If you want to do QA, you must have a basic understanding of QC. Personally, I don't like to sit in front of the computer and change the file format every day, especially when the boss goes to a small net in the back, so I have to remember. I feel dead every time I go to QA. I really don't like it. If you like paperwork or something, QA.
