Be sure to complete Part 1 BEFORE embarking on Part 2. This calendar management section is so important to our positions, so we had to extend it to two parts. You must master the calendar. It is the saving grace for hiccups, early arrivals, overlapping meetings, cancellations, travel mishaps, and time zone mess-ups. A poorly run calendar can create disappointments, harsh conversations, and team discombobulations.  You must know and check the schedule regularly to ensure everything is in sync.
