I'll never forget the time shortly after switching into industry from a purely laboratory workplace, that I had my first encounter with a professional project manager. I got so pissed off that some un-introduced remote person on a conference call was try to tease out what all my "tasks" where, when they would be done and in what order (as well as when everyone else's would be done).

Depends on the quality and style of the PM, but a good one is worth their wait in gold. By coordinating the meetings, managing the dates, and keeping everyone accountable, it takes those burdens off other team members, letting them focus on the work.
