This case study examines how a major North American financial institution with more than 2,500 branches transformed its application deployment process using ARIS. Previously burdened by complex manual compliance reviews across 1,800 enterprise applications, the bank implemented a three-phase solution: converting static documentation to data models, automating business logic, and implementing straight-through processing (this third phase is currently underway). The results were significant: compliance review time reduced from a 5-day SLA window to being nearly instantaneous, senior architect time allocation decreased from 30% to under 5%, and deployment error rates improved from 11% to 1%. This transformation enhanced speed, reduced costs, improved compliance, and provided clear visibility across the financial institution’s application portfolio.
