Being A Low Cost Provider

WORLD CLASS
LOW COST LEADER

Power Tuning Legacy Processing
PART II – PIRANHAS (Pre TRAMS Processing)

Warning Indicators

 Escalating Unit Costs
 Resource Intense
 Extensive Redundancies
 High Maintenance
 Diminishing Breadth of Knowledge
 Cracks are Wider
 Crevices Deeper

Money Pit Profiles

 Stealthy Piranahs
 Multiple
Variations of Single Function
 Comprised of Single Function Programs
 Running Many Time per Day

 Gigantic Killer Whales
 Flagship Jobs Visibly Consuming CPU/DASD
 Heavily Redundant File Content
 Uncontrolled Resource Scheduling
 Non Integrated Cross Application Development
