Rebuilding an aircraft on the fly

Rebuilding an aircraft on the fly

At trivago we started with an iterative rebuild of our user interface in the beginning of 2015. Next to establishing a pattern library and thereby introducing a Design System we started to rethink the way we build our user interfaces in code and design. We adapted several methodologies like Atomic Design, changed our design development workflows, did a CSS refactoring – called Project Ironman – , improved our front-end stack and changed the way we build our assets and started to rebuild the core UI components of our main product in 2016.

The talk will provide insights in our journey with rebuilding our UI at large scale in an iterative way. It will present the challenges we encountered in code, design and our processes and how we solved them. The outcome will be highlighted with real data and some of our business metrics. However it will also show some of our mistakes we did while integrating the Design System and will present the lessons we have learned out of that.

    Definition
 CSS Framework This is the front-end code and production-ready

    design assets. The CSS framework is referenced and consumed by the product(s). It is a modular, scalable, and extensible tool that fosters rapid development and typically confirms to a CI/ CD development environment. https://medium.com/@NateBaldwin/clarifying-our-style-guide-nomenclature-ab72358ee111#.nduusckg1
  3. 7.

    This is the documentation resource for the design system. Since

    the design system is purely code and assets, the style guide is a site to demonstrate the UI patterns with references to aid in implementation and usage. Definition

    Definition
 Pattern Library This is a library of standardized UI

    patterns. They are the final designs, and can be delivered in the form of a repository of design files, or a symbol library/UI kit. It is the resource for designers to build from. https://medium.com/@NateBaldwin/clarifying-our-style-guide-nomenclature-ab72358ee111#.nduusckg1

    Definition
 Design System The entirety of the standardized UI patterns,

    framework, assets, and documentation, as well as the processes and people involved. It is the ecosystem that drives and supports the unified evolution of the product(s). https://medium.com/@NateBaldwin/clarifying-our-style-guide-nomenclature-ab72358ee111#.nduusckg1
