Maintaining a design system goes beyond building components — the real challenge is the rituals, cadences, and documentation that keep teams engaged. Key practices include cataloging standup notes and AI summaries for async catch-up, layered documentation (anatomy, properties, usage, behavior) supplemented by Loom walkthroughs, a central Figma project housing roadmaps and governance models, and a component tracker to measure completeness. Communication rhythms span weekly office hours (split by design and dev), monthly leadership updates and roadmap reviews, quarterly product syncs and workshops, and yearly governance and onboarding reviews. A design system MCP server is highlighted as an emerging tool to prevent AI-driven component drift. Satisfaction surveys and repo coverage metrics help demonstrate value to stakeholders when direct productivity measurement is difficult.
