Design Systems 101 for Growing Product Teams

7 min read 2026-03-29 Sofia Reyes

Most 'design systems' we inherit from clients are a component library without the rules for when and how to use each component. A real design system documents decisions, not just assets.

Start with tokens, not components

Color, spacing and type scale tokens are the foundation everything else builds on. Defining these first - and naming them by purpose, not appearance - makes the system far easier to theme and extend later.

Document states, not just defaults

A button component isn't done when the default state looks right. Hover, focus, disabled, loading and error states need explicit documentation, or every team member will improvise differently.

  • Default, hover, focus, active, disabled and loading states minimum
  • Explicit spacing rules between components, not just within them
  • Usage guidance: when to use this component vs. an alternative

Governance matters more than tooling

Storybook, Figma or Zeroheight are all fine tools - the harder problem is deciding who can add new components and how deviations get reviewed. Without governance, systems drift within a year.

Frequently Asked Questions

Once more than two or three people are shipping UI regularly, the consistency cost of not having one usually exceeds the cost of building it.

Existing libraries like shadcn/ui are a reasonable starting point for early-stage products; custom systems earn their cost once your product has a distinct visual identity to protect.

Really useful breakdown - the point about start with tokens, not components matches exactly what we ran into last quarter.
