"we give free ride on environmentals, floor space and staffing. "
UGh...this is where the z tends to shine on environmentals, floor space and
many times staffing. By giving a free ride in these areas, the z platform,
whether it is z/OS, z/VM, z/TPF or z/Series Linux are placed at a SEVERE
disadvantage.
Yes I know I now work for a company tied to the Z platform, but I did my original TCO
study when I worked for a NYC based firm and yes other platforms thought we shouldn't
include those issues in the cost model "because there wouldn't be any
difference"....HA. When floorspace in NYC was going for $90 a sq foot, the cost
difference between a z box and a room full of servers is big, also when we pay some of
the highest electrical rates in the country, the cost of cooling all these heat
generators makes a HUGE difference.
So giving a free ride to both platforms in NOT equitable treatment, in fact it
is shifting the balance in favor of those platforms that waste environmentals.

Selecting a valid methodology requires visiting your creative
accounting department for their interpretation of accepted accounting
practices.
I say creative because I have seen items capitalized when they should
probably have been expensed somewhere else. The opposite is true as
well.
We try to chage based on incremental cost (going back to fix our
costing would be a nightmare). Even then, we give free ride on
enivronmentals, floor space and staffing. We have a few common setups
(e.g. guest with so much memory and share of CPU), then charge
according to that share regardless of how much they actually use.
DASD is based on allocated regardless of how much is used. We try to
follow the KISS principle since no matter how complicated your
allocation algorithm turns out to be, I can bet that it will be full
of loop-holes and faults.
My adivse, work with your accounting department on something they
understand and matches your budget and the accounts within that
budget.
If you have a choice, run the other way and avoid this project.
