An important consideration in the scheduling of the tasks she's working is
not only *how many* hours per day she works but *which* hours out of the day
as well. On the surface, simply changing her maximum availability from 100%
to 63% seems like it would work (25/40 = .625) but I'm not happy with that
approach since it implies she's available for any arbitrarily chosen 5 hours
out of the 8 hour workday. Instead, she probably has a regular schedule of
hours when she is going to be there and the tasks she's assigned to should
be scheduled to take place only during those hours. Therefore you need to
get her on a resource calendar that reflects that reality. Depending on
when the change of status takes place you could do that by modifying her
resource calendar (Tools ChangeWorkingTime HerName) to show all dates have
new working hours by clicking the weekday column heading labels and changing
the hours to non-default times, or if changing her full time hours to part
time will screw up the tasks occuring before her status change, by selecting
the work days manually in each month following the change and posting new,
non-default, work hours for her for each date. You'll need to do each month
one at a time with the latter method but that really isn't much of a hassle
to do - you can do each month in one swoop by using [cntrl] click and drag
to select all the wordays in each week in the month and that would allow her
resource calendar to show, for example, M-F 0800-1700 for all dates before
July 1st and M-F 1000-1600 for every workday after that.
