Twelve things wrong, and the one I fixed first
I spent a morning reviewing a low-code automation someone else had built. It worked. Forms came in, notifications went out, the right people got alerted. By the end of the review I had twelve things written down that were wrong with it, and the most useful thing I did that day was not hand over the list of twelve.
Working and maintainable are different properties The flow did what it was asked to do, every time. That is not nothing, and it is worth saying out loud before anything else, because a review that opens with a defect list teaches the author that shipping working software counts for nothing.
