I believe that for ongoing long term operations, NASA and DOD
standards are 6 shifts worth of people, however you juggle the
particular shift lengths / schedules.  I.e., NORAD, NASA ISS / Moon
mission mission control, etc.

You can do it with 5, but people need time to get sick, take
vacations, go to training, etc.
