When arranging meetings for your direct reports, you may first need to check to see if a teleconference and/or web conference will be needed. If so, arrange for those first, and add the info to the meeting you're setting up. This happens so often for my managers, and they forget to ask me for the additional conference info ahead of time, so we're constantly updating meetings, rather than including it all at the start.
Another tip...when you schedule a meeting, you need to check to be sure invitees are free to attend. Ask the chair which invitees MUST be there, and use that as a litmus test for the time and date.
Advise the chairs of responses received later on, as well--so they'll have a list of participants to check off as they arrive.
