Thanks. 1997/1997 posts -- and CP/67 reference! -- shows this is a
timeless concern!

Query for Destination z article on chargeback systems
I'm writing article for Destination z -- http://destinationz.org/ --
giving tips on chargeback systems.
Long ago I posted about this subject. Here are two.

We no longer charge for CPU time. When we upgraded from our 360-67 to
an Amdahl 470V/6, we took care that users would see the same bill for
the same work. It seemed to make sense at the time. We upgraded to a
V/7, V/8 and 5890-300E. Each time, we increased the CPU billing rate
so users would see the same charge for the same work. We also kept
the charge per DASD kilobyte the same when we upgraded from 2314 all
the way to 3390.
At the end, on the two engine 5890-300E, we were billing at a rate of
about $50 million per CPU-year. We bought two 5890s. The first one
started out as a 180E, for which we paid $1.2 million. Over time it
was upgraded to a 300E. The other was a 300E purchased later on the
used market for $43,000.
IMHO, if you are going to charge for computing resources, your charges
must be in line with your costs or you will drive away all of your
customers. This kind of scheme is probably one of the reasons that
some users believe that it is cheaper to run on other platforms.

... any chargeback system should be
kept as simple as possible. For example, we have been trying to figure
out how to handle billing for central printing of output generated from
outside of MVS: UNIX, PC, etc. When I showed the announcement for a spiffy
new IBM color laser printer a while back, he got really wide-eyed, but he
wondered how he could get good accounting data to charge back to the non-MVS
users. I told him that for that kind of output, we could just charge users
by weight when they came to pick it up.
