Great question. I can’t recall any standards around this topic, and iirc it came down to common practices. I read a couple of texts to build some fundamental knowledge that I could say I had a reference for. Now I can pass it on to you. Had to open up my Apple Books library to find these again, but: TECHNIQUES OF FLOW-CHARTING Louis A. Schultheiss IBM Data Processing Techniques Flowcharting Techniques I pulled these down from some searches on UML diagramming some few months ago since I needed to diagram some envelope encryption work for a team with a previous employer. The UML-generated code thing is prior to my time, but basic flowcharting techniques on their own are a nice to have skill. You don’t need to memorize endless shapes, but a few common ones like those in the texts above will convey almost everything you’ll care about day-to-day. In my experience, this isn’t a skill you have to exercise often, but if you can do it without being overly sophisticated, some people may appreciate having a diagram now and again for large systems, or involved processes.
