There's a lot of history here, going back centuries. The military has put much effort into designing written communication. There's the classic 5-paragraph operations order format. There's the "bottom line up front" style, which for information rather than orders. The military makes a very strong distinction between info documents and orders.
Diplomats have some traditional formats, too.[1] Most correspondence is formal. Sometimes there's an "appreciation of the situation" attached to correspondence from a mission to its state department. That's an informally written summary of what the writer has observed and what they think is going to happen.
An amusing read is "How to Live though an Executive", which is nominally by L. Ron Hubbard, the Scientology guy, but was really written by Richard DeMille. This is from 1953. It's someone trying to invent Slack, before computers. It's done with wallboards, clips, carbon paper forms, tear-off tickets, and people called "communicators" doing the paperwork. It was never used. Too complicated pre-computer. The basic concept is a trouble ticket, with an organized system to insure that handing off the problem to someone doesn't mean it gets lost to follow-up.
