In the world of frontend development, ensuring a consistent user interface is crucial to delivering an exceptional user experience. Have you ever used an application where every page felt like it was designed by a different team? Buttons with varying styles, inconsistent colors, and an overall fragmented experience? This is exactly what a Design System aims to solve.
What is a Design System?
A Design System is a structured set of rules, components, guidelines, and design principles that ensure visual and functional consistency across one or more applications. It goes beyond a simple component library by incorporating design guidelines, code specifications, and brand values. In short, it is a comprehensive guide to building seamless and effective user interfaces.
Why implement a Design System?
1. Consistency
A Design System ensures that the user interface remains uniform across all pages and features of your application. This allows users to navigate seamlessly, encountering familiar and predictable elements at every interaction. It also guarantees consistency even when multiple teams develop different parts of the application.
2. Boosting Developer Productivity
With pre-designed components and clear design guidelines, developers save time and effort when creating new features. This accelerates the development process while maintaining high visual and functional quality. For example, each team doesn’t need to reinvent and test their own buttons while ensuring they align with the Vaudoise brand identity.
3. Improved Collaboration
A Design System serves as a shared foundation for design and development teams, fostering better collaboration. It minimizes misunderstandings and aesthetic inconsistencies, creating a smoother workflow and a more unified product.
Key Elements of a Design System

A reference for colors, fonts, sizes, and other design attributes that reflect Vaudoise’s visual identity.
📌 🔧 Reusable Components
A shared library of standardized components such as buttons, forms, cards, etc., ensuring visual harmony across applications.
📌 📏 Design Guidelines
Clear instructions on how to use components, colors, and typography consistently across applications.
📌 📄 Technical Documentation
Detailed guidance for developers on how to correctly implement each component and adhere to design principles.
📌 📈 Scalability
Designed to remain relevant and effective in an evolving environment while supporting continuous product and team growth.
📌 🔄 Process
A structured workflow for creating and updating components based on real needs and feedback.
What does it look like in practice?
Before sharing our own implementation at Vaudoise Assurances for our customer-facing frontends and what we've faced off (note: the website is not yet migrated 😇), here are some well-executed public design systems worth exploring:
- Decathlon Design System
- Atlassian Design System
- Dell Design System
- Material Design
- Fluent 2 Design System (Microsoft)
- Carbon Design System
- Backstage Design System
Most of the examples above are open-source, so feel free to explore and get inspired! 😎
A well-implemented Design System is not just a time-saver for teams—it’s also a powerful tool for creating better user experiences. At Vaudoise Assurances, we’ve embraced this approach to ensure quality and consistency across our interfaces for the best customer experience. Stay tuned for more insights into our implementation! 🚀
