Design Systems Worth Building: A Practical Guide

A system only matters if people use it

Unused Figma libraries are expensive wallpaper. A good system reduces decisions and matches code.

Start small (week 1 kit)

Documentation that ships

Each component doc:

• When to use / not use
• Code example (copy-paste)
• Accessibility notes (focus, labels)
• Do / Don't screenshots

Adoption tactics

• Match Figma layer names to code props
• CLI or snippet for common patterns
• PR checklist: "uses design system button?"
• Office hours first month — answer "which component?"

Anti-patterns

• System team blocked from product work for 6 months
• Tokens nobody maps to Tailwind/CSS variables
• Breaking changes without codemods

TL;DR

Ship the primitives that appear on 80% of screens. Grow with real product pressure, not theory.
