Great handoffs start long before a file is marked ready. The strongest teams create shared understanding continuously, so development begins with fewer surprises and better context.
Align On Intent
Specs should explain why a choice exists, not only what pixels to reproduce. Intent helps engineers preserve the experience when technical constraints appear.
Document Edge States
Empty states, loading states, errors, and long content often decide whether a workflow feels polished. Treat them as first-class design work.
Pair Earlier
Invite engineering feedback while flows are still flexible. Early pairing catches complexity before it becomes expensive and helps both sides own the result.
Close The Loop
After launch, review what changed during implementation. Those differences are a useful signal for improving the next design cycle.
