I've been doing some cal/QC functions recently after years not touching it. Since I last did it I've forgotten some of the knowledge that is just assumed. The answers to my questions are documented, but not in a places that is accessible from the production side and has lived as community knowledge in production. I've been making a list and updating the documents to fill in some gaps.

Unfortunately some of the production people aren't comfortable enough pushing for changes in the documentation so some of my job now is to ask what they've noted and get it added.
