Design System Glossary

Design system governance

Design system governance is the set of rules and rituals that decide what enters the system, what changes, when versions ship, and who has the call when teams disagree. It includes the contribution model, the review process, the deprecation policy, and the roadmap. Without it, systems drift — components fork, tokens duplicate, and trust erodes.

Models range from centralised (a core team owns everything) to federated (product teams contribute under shared rules) to mixed. The right one depends on team size, product diversity and political reality. Our piece design system governance best practices covers the patterns that actually hold up over multiple years.
