I've worked for, and as a customer of, many sites with chargeback in place. Your two vectors were RARELY taken into account! Some even tried to do capacity management with the data.
"Oh look! The unit cost per transaction is going down! We DO NOT need an upgrade!" Funny thing, aside from whether the metrics were correct, the unit cost was going down because we were using the dead-space at night, due to opening up access by the INTERNET; the day-time peak (which was driving need) was still increasing. Over-night access was getting a 'free ride'. But, the bean counters were still using the data to 'plan'. -teD Original Message From: Timothy Sipples Sent: Thursday, March 10, 2016 01:19 To: [email protected] Reply To: IBM Mainframe Discussion List Subject: Re: Does everybody use chargeback?

I disagree, unless the "etc. properly" part is truly enormous in scope. I notice you didn't mention anything outside the mainframe, for example. Is everything else free? :-) Here's another gigantic problem. Even if (big if) you could precisely measure and allocate marginal costs at every moment, is cost the *only* factor? No, it's only one factor...along with (vectors of) functionality and quality. -------------------------------------------------------------------------------------------------------- Timothy Sipples IT Architect Executive, Industry Solutions, IBM z Systems, AP/GCG/MEA E-Mail: [email protected] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
