How Do You Eat an Elephant? An Architecture Modernization Story.

Modernizing legacy systems is rarely just a technical challenge—it’s often about whether an organization can keep moving forward at all. We’ve seen this firsthand, from a Swiss financial firm with a core platform that had become a fragile black box, to a 27‑year‑old factory system running non‑stop, where changes felt risky and knowledge lived in just one head.
Different industries, same pattern—and the same lesson: don’t try to do everything at once. We broke modernization into small, safer steps, started by understanding what really mattered to the business, and made sure each step delivered something tangible.
This talk isn’t about shiny tech or buzzwords. It’s about the human and business side of modernization—reducing risk, keeping teams on board, and rebuilding trust in systems that absolutely cannot fail. Expect practical lessons, honest war stories, and yes, even a surprise Tweety Bird cameo.
