Just a guess, but I bet your process for planning a meeting at work goes something like this: You log on to your company calendar, or spreadsheet, or whatever you use. You pull up the conference-room tab. You look at everyone’s schedules and the schedules of the various always-overbooked rooms, and you're already exhausted. You finally find a time and a space and send out an invite. Several people email to ask if you can change the time. One of them is your boss, so you look for another time and another room.
