Just commenting FYI others reading the thread. Project doesn't monitor or
identify under-usage at all. The reason is that the project's universe is
circumscribed and by no means the totality of the activities of the firm.
If Joe works 8 hours on Monday yet you have chosen only to assign him in the
project for 4, Project assumes you had a reason for that decision and he is
already committed for the other hours to some undefined something outside
the universe that is known by MS Project. Otherwise you'd have assigned him
100% from the start, right, since the over-riding objective is get the
project done asap? Staffing decisions should always made by people, never
the software (which is why the out-of-the-box task type is fixed units,
btw). If you want to insure the resources are always fully utilized, never
assign them at anything except 100%.
I'm curious why your client wants to monitor the contractor's resources to
make sure they're utilized properly. Isn't that part of the contractor's
business organization that doesn't really affect your client at all. The
contractor has agreed to deliver X product by Y date for Z cost. How he
goes about it is up to him - how he organizes his workers to get the job
done is essentially a black box as far as the client who hired him is
concerned, as long as the contractor delivers on-time.
