A journey map lays the stages a person moves through toward a goal — awareness, consideration, purchase, onboarding, advocacy — along a horizontal timeline, then overlays a vertical emotion curve showing what they do and feel at each stage. Touchpoints, thoughts, feelings, and pain points sit underneath each stage so you can see exactly where the emotion line drops.
It's easy to confuse with a user flow, but the two serve different purposes. A user flow diagrams screen-to-screen navigation inside one product; a journey map covers the much wider experience — including moments outside the product entirely, like seeing an ad or getting a recommendation from a friend. The protagonist isn't a screen, it's a person's experience.
Wherever the emotion curve drops sharply is the highest-priority place to dig in. Finding that one dip and chasing its cause is the actual point of drawing the map.
When to use
Use it when you need the big picture of where drop-off or frustration happens across an entire experience, not screen by screen. If you only need navigation paths, a user-flow diagram is enough.
