Case Study: a large federal agency modernizes its mission-critical financial system with CGI AI-powered insight

a large federal agency delivers months of engineering insight in hours with CGI

A large federal agency faced significant technical risk when it inherited a mission-critical, undocumented financial management system with redacted source code. They needed to modernize this opaque system but could not understand its inner workings. To address this challenge, they partnered with vendor CGI, which applied its AI-powered IT modernization offering.

CGI used specialized agentic AI teams to perform targeted analysis, reverse engineer the codebase, and visualize its architecture in a dynamic knowledge graph. This process, supported by continuous human oversight, delivered comprehensive documentation and a modernization-ready blueprint in hours instead of months. As a result, CGI provided the agency with a clear understanding of their system, significantly reducing technical risk and creating a solid foundation for future modernization.
