Screen flow
A user flow built from actual screens or mockups instead of abstract boxes – the most literal, walkable map of a product.
Take a user flow, replace its abstract steps with the real screens (or their mockups), and you have a screen flow – a walkthrough you can point at. It’s a mid-to-late-stage artefact: worth wiring together only once the structure (from a task flow) and the visual direction (from mockups) are both settled enough to be worth connecting.
