Design Systems
Build once, use everywhere. Consistency at scale.
What is it?
A design system is a collection of reusable components, patterns, and guidelines that ensures visual and functional consistency across a product or suite of products. It includes tokens, components, documentation, and governance.
When to use it
Invest in a design system when your product scales beyond a single team, when inconsistency becomes a problem, or when development velocity is hampered by rebuilding the same patterns.
How to do it
Audit existing UI patterns and identify recurring components.
Define design tokens: colors, typography, spacing, shadows.
Build a component library starting with the most-used elements.
Document usage guidelines, variants, and accessibility requirements.
Establish governance: who maintains the system and how contributions work.
Pro tips
Start small. A well-documented button component beats 50 undocumented ones.
Design systems are products, not projects. They need continuous investment and a dedicated owner.
