High-Speed Agility: Transforming SNCF TGV IT by Impact, Not Doctrine
summary
Nicolas Sigalo and Isabelle Petit Rome describe how SNCF TGV’s IT department reinvented value delivery over 2.5 years by running three successive Agile Release Trains (from 2023) covering the whole customer journey. They explain practical changes — adopting PI Planning and stable agile rituals, moving from project-driven ‘bulldozer’ work to value-oriented flows, reorganizing from technical silos into value-aligned teams, and using tools like Miro and Jira (with planned AI integration) — emphasizing impact-driven, incremental transformation rather than strict dogma.
