INTRODUCTION

English translation pending.

CORE DEFINITION

Story mapping, developed by Jeff Patton, places user activities along the horizontal axis in the order they occur and stacks user stories beneath each activity in priority order vertically. Horizontal slices define releases, beginning with a minimum viable version. The core claim is that a flat backlog loses the narrative of the user's journey and the levels of value, so a two-dimensional map lets a team see the end-to-end flow and the sequence of delivery at once. The qualification is participation, since a map drawn by one person and never updated becomes another stale document.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Build the backbone: list the main activities the user performs, in real order, along the axis. - Stack the stories: place individual stories under each activity in priority order. - Slice the releases: draw horizontal cuts that define the first viable version and later increments.

Anchor fast decisions

A backlog ordered by priority alone answers what to build next but not how the pieces fit into a user's experience, so teams optimize features and miss the journey. Adding the horizontal axis restores the sequence, which makes dependencies and gaps visible, while the vertical axis keeps priority in view. Horizontal slices then align releases with end-to-end outcomes rather than with modules, which means the first release delivers something a user can actually complete. The map only carries this information while it is shared and current.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

List the user's main activities in the order they occur. 2. Place user stories beneath each activity in priority order. 3. Draw horizontal slices that define the first viable release and later increments. 4. Review the map with the whole team and update it as understanding changes.
