The case clearly shows the variety of jobs PM does, variety of people s/he interacts with.
Case shows that PM has to plan his/her day in details, because each minute has the meaning, s/he even has to plan for listening to music otherwise s/he will never find the time.
Case shows the difficulty of following up on each team's progress, as there are so many details and specifics in each team /department; and it's real to omit the relevant information while doing such a complicated job.
