After you run the Sub-Capacity Planning Tool, you send the output to IBM and receive a cost analysis in return. If you have used the Sub-Capacity Planning Tool to create outputs for several months because you have seasonal variations in your system utilization, or for +1 year and +2 year plans, send all the output spreadsheets to IBM for cost analysis. The cost analysis shows your present software costs and what they would be if you used sub-capacity pricing. The cost analysis shows you whether sub-capacity pricing will save you money now or in the future.

If sub-capacity pricing has no present or projected future advantages for you, you might still want to repeat the process a year or 18 months later. But, for now, you are done.

If sub-capacity pricing has current or future advantages for you, you will need to review the IBM® terms and conditions for your current or planned configuration.

Whether or not you decide to use sub-capacity pricing for your current configuration, you need to establish a regular review of your software inventories, capacity growth plan, and software pricing analysis. Most of these tasks are usually performed by the software asset manager but the regular reviews of your inventories and plan should be done by the whole planning team.
