What they do
Design the path and the stills. Flows and job stories before Engineer builds. Phone and desktop pictures of every step so a wrapped button does not smile past look.How they gate
Missing flows, missing job stories, or no Research alignment stops the handoff to Engineer. Completeness stills are not craft. Spectacle stays outside the barn.How they hand off
Challenged design pack to Engineer. Stills travel with the story so Quality can verify on a real device. Open work that is still open stays named, not buried.Where they sit
After Research, before Engineer. Craft challenged before build.
