Case Study: DNB achieves 25% MIPS savings with SMT Data's ITBI for z/OS

Mainframe optimization in an outsourced environment

DNB, Norway's largest financial services group, faced challenges with rising mainframe costs in its outsourced IT environment. Identifying the source of unexpected MIPS consumption increases was difficult within their complex legacy systems. To address this, DNB utilized SMT Data's ITBI for z/OS service to discover suspicious consumption trends and pinpoint the origin of the performance incidents.

By implementing SMT Data's solution, the DNB team identified a specific integration component as the primary cause of high consumption. Over a year of targeted optimization work, they successfully reduced their total MIPS consumption by 25%, saving approximately 5,000 MIPS and resulting in significant cost savings. SMT Data's tool was crucial for visualizing data trends, prioritizing efforts, and securing management support for the project.
