Mainframe Software Portfolio Optimization Services
Stop overpaying for your z/OS stack. We’ve helped clients save over $1B USD by eliminating licensing waste.
Lower monthly license charges
Identify and eradicate “Shelfware” and legacy tools with overlapping functionality, such as duplicate performance monitoring utilities.
Simplify vendor management
Consolidate your software footprint to gain powerful technical leverage for a stronger negotiating position at contract renewal.
Reclaim system capacity
Free up MSUs consumed by unused, misconfigured, or inefficient software agents and background tasks.
What is mainframe software portfolio optimization?
Mainframe software portfolio optimization is the strategic process of auditing your z/OS software stack to perfectly align licensing costs with actual technical utilization.
By analyzing historical SMF data records and vendor contracts, we identify products that are no longer required, remove duplicate functionality, and uncover opportunities to negotiate highly favorable terms based on real-world usage.
Our three-phase software portfolio optimization process
We’ve helped clients save over $1B USD leveraging a proven methodology that converts system forensic data into an actionable financial and operational roadmap, ensuring major cost reduction without ever compromising system availability.
Forensic Assessment
Independently evaluating all z/OS systems, software lists, and contracts. We map real-world utilization to identify duplicate functionality, under-used products, and potential compliance exposure from unlicensed software.
Strategic Action Plan
Building data-driven ROI models for software removal and providing the exact “technical ammunition” needed for vendor negotiations.
Managed Execution
Managing the safe removal of legacy tools while rigorously monitoring for hidden dependencies within your production batch cycles.
Overcoming the hidden costs of software bloat
Navigating complex ISV contracts and software interdependencies requires a precise blend of deep-system forensic data and procurement strategy.
We understand that internal stakeholders can often be reluctant to retire legacy tools due to perceived stability risks. As true z/OS system experts, we specialize in resolving these internal obstacles to safely realize maximum potential savings while ensuring your environment remains entirely resilient.
What is the difference between a software inventory and a rationalization audit?
An inventory only lists what is installed. A rationalization audit uses SMF and RMF data to measure actual execution frequency and resource consumption. Many “installed” products haven’t run in months. We help you cancel those renewals safely.
How do you handle software that is required for compliance but rarely used?
We categorize assets by “Business Criticality vs. Utilization” and isolate right-sizing opportunities, such as shifting to a single LPAR or restricted user groups instead of costly enterprise-wide licenses.
Can CPT Global assist with the actual vendor negotiation process?
Yes. We provide SMF-backed technical ammunition that shifts negotiations away from standardized price lists and toward value-based agreements reflecting your true operational footprint.
What are the risks of decommissioning legacy software tools?
The primary risk is a hidden dependency. We mitigate this through detailed address-space analysis and extended “silent-mode” testing before formal decommissioning.
