A free, interactive web-based resource created to guide teams through the process of planning, building, and scaling a design system. The site presents a comprehensive, categorized checklist that spans foundational elements (like tokens and style guides), component development, tooling, documentation, governance, and adoption strategies. Each checklist item is organized by level of maturity—Foundations, Modules, and Mastery—allowing teams to assess their current progress and identify next steps.
Built by Jean Moreno (also known as @JeanGraphic), the resource is both educational and practical. It emphasizes clarity and usability, enabling teams to collaborate effectively across design and engineering. Each section includes links to relevant tools, articles, and best practices, positioning the checklist as a living reference rather than a static document. Whether a team is just starting or refining a mature system, the Design System Checklist supports structured, transparent decision-making throughout the design system lifecycle.
