KEY ACCOMPLISHMENTS
 Saved over $10 million in mainframe capital expenditures, at MCI, by defining and initiating a competitive bid
process for DASD storage resulting in positive financial outlook. Reduced scheduled outages resulted from the
increased planning.
 Reduced the yearly mainframe software expenditure, at Atos and Fujitsu, by about $800k for IBM mainframe
software and SAS by over $250,000 as the result of analyzing of the licenses and eliminating unneeded software
licenses.
 Reduced monthly software license feed by $15,000 -- $20,000 by implementing IBM’s Mobile Workload pricing.
 Improved the mainframe computer usage billing process,at Fujitsu, to provide the finance department the data one
day earlier than the previous process with the expectation of improving cash flow. The process improvements also
implemented restart points, reducing the time required when reprocessing the data is necessary.
