Case Study: Bank of Ireland achieves major mainframe cost savings and 3-hour-to-15-minute batch speedups with Compuware Strobe and iStrobe

Strobe Pays for Itself Before Proof of Value is Complete

Bank of Ireland needed to control rising operational IT costs and eliminate the risk that aging mainframe batch processes could run so long they interfered with daytime processing. With a portfolio of legacy systems and inefficiencies in code and DB2 access, the bank launched an initiative to maximize mainframe efficiency.

They deployed Compuware Strobe and iStrobe and ran a proof-of-value that quickly uncovered inefficiencies traditional analysis had missed—savings that covered the software cost. Results included cutting an overnight batch from three hours to 15 minutes, reducing CPU time in another process from five minutes to 30 seconds, deferring a MIPS upgrade by six months, and making Strobe part of an ongoing optimization program.
