Deutsche Bahn faces complexity from diverse applications, multiple frameworks, and non-functional requirements like accessibility across internal and external teams.
Open source principles enable collaboration with external partners, improve component reusability, and serve as a quality gate for the entire system.
The company supports open source through leadership backing, dedicated time for contributions, architecture guilds, and active internal developer communities.
The DB UX design system was moved from a private inner source model to public open source to better include external partners and agencies.
The system uses Sketch and Zeplin for design tokens via Style Dictionary and Mitosis to generate components for multiple frameworks like React and Angular.
A cross-functional process involves community, accessibility, and brand teams, using pre-releases, Playwright for visual regression testing, and GitHub Actions.
Feedback is gathered from a large internal web development community via MS Teams before being migrated to public GitHub issues for transparency.
While previously used with Stencil.js, the team is not currently using Storybook due to challenges with their Mitosis-based mono-repo and documentation integration.
