You might consider thinking in terms of a work breakdown structure or project map.
This article has some good examples. There’s a specific example for how to chart out staff about mid-way through. (Note - I am not advocating or shilling for Creately.)
You could also just do a free-form connection - MiMind has some interesting example.
miMind is really good and has an interactive outliner. but only allows importing Freemind files at the moment. They are considering implementing export so I'm keeping an eye on it.
I'd recommend miMind. It's a progam for making mind maps that's very easy to use but also tremendously helpful. I've been using it to make family trees for my world for a month or so now, and I love it! I'd definitely recommend checking it out, see if you like it or not
