Clear documentation of design decisions for smoother handoff and better collaboration with developers.
The part that usually gets skipped, and the reason design intent quietly disappears in the build. We document why a design works the way it does, specify the components, define the interactions and — most importantly — write down the edge cases: empty, loading, error, too much content, no permission. Those states are where handovers actually break down.
Typical duration: Typically 5–10 days
Why the design is the way it is, so future changes do not undo the reasoning by accident.
Components, states, spacing, behaviour — precise enough to build against.
Empty, loading, error, overflow, permission-denied. The states that get discovered in production otherwise.
Walked through with the developers, not emailed at them.
