Jacky Hofbauer - zCost Management founder - explains about IBM Mainframe charter:
First, the Mainframe community is strong and still growing thanks to a high investment rate and highly skilled people. The vWLC (variable Workload Licence Charge) process matches the Value statement of the Mainframe Charter. This billing method stipulates that the customer will be invoiced on the capacity of the machine he actually used, not the "full capacity". This allows the customer to control his costs. zCost Management plays an active part in the implementation of this charter as our policy is to save MSUs by creating surplus power or "White Space". Furthermore, AutoSoftCapping has a fast return on investment (ROI) since it reduces the software costs.
