A user journey is a representation of the broader experience a person has while trying to achieve a goal, including stages, touchpoints, context, actions, and perceptions over time.
Take a traveler booking a flight. The journey can begin before they open the product: deciding dates, comparing destinations, checking budget, asking friends, searching flights, booking, receiving updates, traveling, and handling a disruption.
The product experience sits inside that larger journey.
A user flow maps the product steps used to complete a specific task. A user journey zooms out to include context around the task and can span several channels.
The terms overlap. A customer journey often includes the wider commercial relationship such as discovery, purchase, billing, support, and renewal. “User journey” is commonly focused on use of the product or service.
A journey map should not become fiction with sticky notes.
Different roles and contexts can produce very different experiences.
Then you have created a flow, not a broader journey.
A user journey asks: what is the person experiencing before, during, and after the part of the product we can see?
