[SAGE] determining quantity of support personnel

[Eric Mercer <emercer@rad.upenn.edu>]

Does anyone have any pointers to information about how to determine how 
many personnel are required to support a given number of machines.  As 
crazy as it may sound, I'm looking for a number like: 1 person can 
support 100 PCs.

Administration here wants such a number so that they can justify 
increased costs of computer support in the department.  We currently 
have two desktop support people & one unix/network admin (me).  We are 
supporting about 10 unix servers, 3 NT servers, and approximately 
200-300 PCs (win98 - winNT).
