Alignment between disciplines.
WHAT CAUSES DIVERGENCE
Designs produced without reference to what exists Components built without reference to the design system Tokens defined separately in each
WHAT PREVENTS IT
A single source for tokens, consumed by both Designs built from the same component set Regular review of built work against intent
WHAT TO SHARE
Token values, ideally generated from one definition.
WHY
Manually synchronised values diverge immediately.
WHAT TO AGREE
That new patterns are added to the system, not created ad hoc.
WHAT TO ESTABLISH
A process for proposing something new.
WHY
Without one, people build their own, and the system fragments.
WHAT TO REVIEW TOGETHER
Built interfaces against designs, before release.
WHAT TO FLAG EARLY
Designs using values outside the system Designs requiring components that do not exist Patterns duplicating something existing
WHAT TO DECIDE
Whether the system changes, or the design does.
WHAT TO DOCUMENT
The decision, either way.
