The optimization potential identified by us in the consultation will contain different levels of savings, depending on the company and the existing approaches in that company. For example, the effort expended on user interface development can be reduced from 13 to 4 person-days by using the PASS Software Factory. Millions in operating and maintenance costs can be saved by migrating legacy applications to state-of-the-art technologies. And material and process costs can be drastically reduced by moving to the electronic processing of invoices.
