title structure at you design agency

I work for a small (10 person) agency with some large accounts. Right now our office is broken into 2 teams: 2D (graphics) and 3D (architecture). Each team has a “creative director” and 3 “designers” that all do entirely different things. In order to give existing accounts and potential new clients a more thorough depiction of our actual capabilities, we are exploring restructuring the titles to be a little bit more descriptive. We want to move away from the old school structure of creative directors, art directors, designer I, designer II, etc. etc… use titles that actually speak to what we specialize in.

That said, I’m wondering if others on this forum can give a brief description of how their companies are structured and a breakdown of titles.
