Challenge
A leading Canadian bank, one of the "Big Five," had been outsourcing its mainframe operations for over 20 years.
Costs continued to escalate, creating a significant financial burden.
The bank needed to reduce these costs without disrupting critical operations or requiring major application changes.
CPT Global’s Actions
CPT Global was tasked with reviewing the bank's CPU usage and recommending changes to reduce costs.
CPT worked closely with the client to identify untapped savings and resolve a system issue that prevented the bank from leveraging over 90% of its mainframe capacity—all without requiring any application changes.
CPT also provided guidance on improving mainframe performance, security, and resilience.
Results
- 18% cost reduction ($Millions saved in hardware upgrades)
- 8% CPU savings through verification and implementation.
- 10% CPU capacity increase at no additional cost.
- $6.8M saved over 2 years by avoiding hardware upgrades.
CPT Global’s strategic approach allowed the bank to cut costs significantly while improving mainframe capability and performance.
