#428 - Modernizing IGA with Thomas Zarnhofer
Notas del episodio
Recorded live at EIC 2026 in Berlin, Jeff and Jim sit down with Thomas Zarnhofer, IAM Architect at a major retail company in central Europe. Thomas shares his experience leading a full IGA transformation from a decade-old on-premise system to a modern cloud-based platform. The conversation covers the shift from a contract-based to a person-based identity model, the importance of cleaning data before migration begins, a three-phase framework of Foundation, Migration, and Adoption, lessons learned from running two systems in parallel, and a look at how AI could make IGA predictive. The episode ends with Thomas's tips for visiting Austria.
