The decision that matters
Start with shared typography, spacing, color roles and interaction states. Add components for recurring patterns such as status, validation, empty lists and destructive confirmations. Document when a pattern should be used and what information it requires. Keep accessibility behavior in the component contract so each application does not reinvent keyboard handling, labels and focus treatment.
A practical scenario
A company suite may share a brand mark and navigation frame across work, knowledge and customer tools. A shared record editor can also enforce consistent image handling and save feedback. However, an invoice approval and a casual note do not need identical information density. The system should support those differences without fragmenting the visual language.
Before you ship
- Name tokens by purpose rather than a specific screen.
- Document states such as loading, error and disabled.
- Version shared packages and verify representative consumers before rollout.
A useful next step
Pick a repeated workflow that currently differs across applications. Build one reusable pattern, test it with real content and document the decisions it encodes. Expand the system through demonstrated reuse rather than designing a large component catalog before the product needs it.
