Write/prepare an agenda listing the items to be discussed
Indicate the duration and responsible/lead of each
Aim for a meeting to last under an hour. If more time appears to be required, then prior work should be done in order to reduce the amount of time necessary for the meeting.
Define the list of invitees, try to keep it short, possibly under 6 people
Share the agenda with all the attendees
Schedule the meeting around boundaries (beginning/end of day, before/after lunch)
In the case where a recurrent meeting needs to be scheduled at a different time than usual, specify in the body of the message the reason of the change.
