Consistency is speed
A design system gives teams shared decisions for spacing, typography, color, components, states, and accessibility. That means engineers spend less time interpreting screenshots and more time shipping product.
Start small
Document buttons, inputs, cards, tables, modals, empty states, and navigation before creating a large component library. The system should match real product usage.
Keep it alive
Design systems fail when they become separate from delivery. Review new product screens against the system and update components when real use cases prove a better pattern.
