Story mapping puts the focus on your users instead of your stakeholders. Using the horizontal line you create a series of categories representing each stage of your user’s journey through your product, from sign-up to using specific features.
You then place these tasks, from top to bottom in order of importance. This allows you to prioritize the order of the features you’ll work on in the future. At the end of the process, you draw a line across all the stories to divide them into releases and sprints.
