Different places adopt different philosophies.  Having been the MVS chargeback 
administrator in the past, I can say that no method is perfect.  My suggestion 
is to familiarize yourself with the research of those who have gone down this 
road before.  A good place to start would be the Web site of the IT Financial 
Management Association http://www.itfma.com/.  It would pay to own a copy of 
Chargeback and IT Cost Accounting, by Terry Quinlan, available at 
http://www.itfma.com/displaycommon.cfm?an=1&subarticlenbr=10.

Subject: Chargeback reporting

Hi all

I want to send senior management a chargeback report each month - not actually 
to chargeback but to illustrate in pounds and pence what we're doing on the 
mainframe. Partly I hope to show that, overall, we're cost-effective per 
business transaction compared to some of the other processing platforms, etc.. 
and also to show the development people on a job-by-job basis what their "big 
hitters" are and identify targets for efficiency improvements etc (we're toying 
with the idea of signing up for sub-capacity licensing).

Presumably I should use SMF type 30 records as a basis for this (rather than 
RMF records?) Would you use the values for CPU seconds, or those for service 
units? Regardless of which, do you take the totals of these, or just the CPU, 
SRB, etc?

In arriving at a cost per CPU second or per Service Unit, What sort of 
financial "inputs" do people typically use? Our z9 was only purchased just over 
a year ago, so I assume the capital cost of that, written down over a period of 
years, should factor, plus the annual software costs and initial purchase 
prices, but also people costs..??

What about disk/storage usage, do you factor those in too?

Sorry, probably a big topic, I know.

If anyone's got any pointers to manuals or documentation on this sort of thing, 
I'd also appreciate it.

Cheers!

Brian
