At a previous employer, I was able to justify the acquisition of a specialty engine to reduce the MSU peak by using Al Sherkow's LCS software. It proved that zIIP/zAAP eligible time would have reduced overall MSU PEAK hours. The actual cost savings came to approximately $12,000 a month...an amount easily justifying the specialty engine purchase and depreciation/ROI within six months.

But you can use on PROJECTCPU in IEAOPTxx to simulate zIIPs and read the RMF reports to see what is reported as zIIP-eligible work. And, you can use the non-zIIP time in that same mode to estimate the probable effect on your 4-hour rolling average CP busy.
