Case Study: Large IT Firm (€2B+ European System Integrator) saves millions in AMS and boosts client renewals with CAST Highlight

System integrator saves millions with application control tower

A €2 billion+ European system integrator serving BFSI, telecommunications and government struggled with project delays and cost overruns in its Application Management Services (AMS). The CIO’s custom dashboard required heavy manual upkeep and couldn’t deliver timely, accurate insights needed to boost client renewals, identify modernization opportunities, or support fact-based RFP due diligence.

The CIO implemented CAST Highlight to automatically analyze application source code, integrate with repositories, and enrich findings with business-context surveys—creating an automated “application control tower.” Within weeks they gained portfolio-wide visibility, eliminated manual reporting (≈1% savings of annual AMS revenue), avoided discretionary and penalty costs (≈3%), and unlocked higher renewal and upsell potential—about a 4% total AMS revenue impact as estimated by the SI.
