THE SHORT ANSWER

Build reusable patterns around recurring problems rather than a large library nobody maintains.

Look for repeated friction

Inconsistent fields, duplicated tables and slightly different confirmation flows create design and engineering work. Identify the patterns causing recurring changes or user confusion. A design system is useful when it reduces that friction. A vast component catalogue created before the product’s needs are understood can become another maintenance obligation.

Start with foundations

Agree typography, spacing, colour roles and interaction states. Then build the controls and patterns that the product uses repeatedly. Include focus, error, disabled and loading states. A button screenshot is not a complete component specification if each developer must independently decide how it behaves during a slow request.

Connect design and code

Document the relationship between the design asset and implemented component. Test realistic content and responsive behaviour. Keep accessibility requirements within the component definition. Shared tokens help consistency, but they do not remove the need to review the assembled page: several individually usable components can still form a confusing journey.

Give the system an owner

Define how teams propose changes, release updates and retire patterns. Start small and expand from actual use. Track whether the system makes delivery easier and reduces inconsistency. Without ownership, a once-coherent library becomes a collection of competing versions that recreate the original problem.

PUT IT INTO PRACTICE

Your next working session.

  • Prioritise recurring patterns
  • Include interaction states
  • Assign maintenance ownership

Bring one real, anonymised example to the discussion. Work through the choices above with the person responsible for the outcome, record the unresolved questions and agree who will investigate them.
