Inventory repeated patterns
Look for buttons, fields, cards, alerts and navigation elements already appearing across the product. Note differences that are intentional and inconsistencies that create confusion. Start with patterns used in important tasks rather than drawing a large library of hypothetical components. A small system is useful when it reflects real implementation needs.
Define states as well as appearance
A button needs more than its default colour. Document focus, disabled and loading behaviour where those states apply. Fields need labels, help text and error treatment. Include spacing and typography decisions that support readability. Without these states, a component library can look consistent in a design file while behaving inconsistently in the application.
Connect design decisions to code
Agree how components are named and how their supported variations map to implementation. Avoid creating many slightly different variants that no one can explain. Include examples showing when to use each pattern. A developer and designer should be able to discuss the same component without maintaining two unrelated descriptions of its behaviour.
Keep ownership lightweight and clear
Name who reviews changes and how existing screens adopt an update. Treat accessibility and responsive behaviour as part of the component’s definition. Use real product feedback to decide what to add next. The system should reduce repeated decisions and errors; if maintaining it takes more effort than the problems it solves, simplify the scope.
Your practical checklist
- Start with patterns used in real tasks
- Document focus, loading and error states
- Align design names with code components
- Assign review and adoption ownership
