Constantly relying on "observations" is incredibly patronizing and I've gotten away from it outside of very formal reporting / performance improvement plans / firing someone.
In my current line of work (and previous one, finance), if you cite observations as the main way of communicating, the other person is just going to cut you off and tell you to hurry the fuck up and tell them what they did wrong.
