Most design systems fail the same way: a beautiful component library nobody maintains. After leading a multi-brand system across three teams, here’s the minimum that actually survives.
Tokens are the system
Color, type and spacing stored as data — not hardcoded values — is what lets one system serve three brands. If your “system” is a Figma file with no tokens beneath it, you have a sticker sheet, and sticker sheets don’t scale.
Components need contracts
Every component ships with three things: the visual, the coded equivalent, and the rules — when to use it, when not to, and what happens at the edges. Undocumented components get reinvented within a quarter; I’ve watched it happen.
A design system is a product, and its users are your colleagues. Ship release notes, take requests, and deprecate loudly.
Governance is a feature
The unglamorous part: a lightweight proposal process for additions, a monthly review, and one person who can say no. Without it the library grows by drift — fourteen grays again within a year.
Start small: tokens, ten components, one page of rules. Grow by decision, and the system will still be saving you time in year three.
