Design Systems
Design System
A design system is a shared set of reusable components, patterns, and guidelines that keep a product consistent and faster to build.
Why it matters
It saves teams from reinventing buttons and forms on every screen, ensures a coherent experience, and helps designers and engineers speak the same language.
In depth
A design system is more than a component library — it includes design principles, tokens, patterns, usage guidelines, and often shared code. It scales good decisions across a team so quality and consistency don't depend on any single person remembering the rules.
Real-world example
Google's Material Design and IBM's Carbon are design systems with documented components, rules, and code that teams reuse.
