## Source excerpt

-- Building Felix, the Design System for Groupon Several new features have been released on Groupon.com recently, such as the QR code in the navigation bar to download the app, and a banner carousel to display multiple banner messages within a single view. In the past, similar product features might take 2-3 sprints to complete, but now all of these features are developed and tested in a single sprint. The reason why we can finish the development and testing efficiently is mainly credited to Felix, the design system we're building for Groupon. What is a design system? Design Systems are not new to the world of product development. There are many successful cases in the industry, such as Google's Material Design, Microsoft's Fluent Design System, IBM's Carbon, Adobe's Spectrum, and so on. With their design systems, these companies have successfully changed the way they design and develop their software products by establishing a set of reusable components and usage guidelines to inform design and development. The result? Delivering faster and better product experiences to our customers, at scale. Felix, the early days In 2020, Groupon's consumer experience design and engineering teams began partnering to bring to life a comprehensive design system-now named Felix-to be used throughout Groupon's many brands, platforms, and products. Initially, I believed a design system to be simply a set of design specifications and component libraries -- an unoriginal concept. After diving into the architectural design and project management of Felix's development with Lead Product Designer, Michelle Witkowski, I realized Felix's true potential: a fundamental change in collaboration between designers and developers. This year, we have built out the initial implementation of Felix, and several of our development teams have begun leveraging it. Through the use of design tokens within Felix, we have developed themes to support Groupon's multiple brands (Groupon and LivingSocial) and plat
