Mike --
Thanks for your opinion on this subject, although it is only an opinion.
There are definitely two schools of thought "out there" on how to track
nonworking time such as vacation and sick leave, and how to use
Administrative projects. One school of thought says that Administrative
projects can be used for capturing nonworking time, since doing so makes it
easy to report on all instances of nonworking time during a certain period
of time. The same school of thought says that Administrative projects can
be used to capture unplanned work, as well. You see this school of thought
reflected in Gerard's original question, in which he has two administrative
projects, one for capturing nonworking time such as vacation and sick leave,
and another for capturing unplanned work.
The second school of thought is what our company, msProjectExperts,
officially recommends to our clients. We recommend that planned nonworking
time, such as vacation and personal days off, should be entered on each
resource's personal calendar in the Enterprise Resource Pool. Doing so will
cause Project Server to automatically reschedule project tasks for each
resource's instance of nonworking time in each project to which they are
assigned. This is a powerful advantage, but the down side is that it is
very labor intensive for whomever has to enter each nonworking time
instance. We further recommend that Administrative projects only be used
for capturing unplanned work and for unplanned nonworking time, such as sick
leave.
My only disagreement with you is that you stated your opinion as if it were
a fact. Hope this helps.
