By about lunchtime of the day after the maintenance window, most of the
remaining problems should have been found. At that point, if it is sufficiently
quiet, the flight director and some of the senior SAs should sit down and talk
about what went wrong, why, and what can be done differently. That should
all be noted and discussed with the whole group later in the week. Over
time, with the postmortem process, the maintenance windows will become
smoother and easier. Common mistakes early on are taking on too much, not
doing enough work ahead of time, and underestimating how long something
will take.
