I am writing a doc about expanding scope & responsibilities of me and another senior person on team. My first draft was very polite, wish washy trying to keep everyone happy but also asking for more ownership type of doc. In my current version I have dropped all pretense and just gone straight out to demanding more. The result is the doc went from 6 pages to 2 pages, is crisp and super direct and just lays it out as it is. I love it, and if it pisses of people, well, thats the goal!
