William, 1 - You state that internal customers are only concerned with chargeback and application performance, yet if that was the case, why are the putting up with web apps with 10-12 second response time and the requirement that they move their hands from the keyboard to the mouse and back repeatedly, increasing user work while they used to have a CICS screen with sub-second response time. 2 - Companies that exclude power and environmental issues (including sq foot of floor space, labor to upgrade power panels etc) in the chargeback are doing themselves a huge disservice. If you have chargeback, don't just charge for part, charge for all.

They are really only interested in the total cost of acquistion or internal chargeback (excluding power and environmentals) and application performance. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
