Service units not only better reflect the work being done, but also gives us a
better idea how that work could map to a different box.
Considering that LSP is what derives service units, then I would say that you
are incorrect.
Service units are almost as meaningless as MIPS.
(Yes, I know
Agreed. Also, consider that the only Chargeback-related SMF data source
providing service units is the SMF type 30 data for address space usage.
Better to calculate and use a normalized (using a user-defined
speed/conversion factor) CPU time metric, derived from the specific SMF / log
data
Agreed.
Try including an extract from the post you're agreeing to.
Or, at least the name.
It makes this response easier to follow.
Thanks.

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

Agreed, Service Units are a better measure for full-fledged chargeback and
capacity planning. They work very well with managers who already understand
SUs. If your management is less than the IBM trained management, they might
not understand Service Units at the beginning.
