What is the purpose of the backbone in a story map?

• A. Represents the top-level flow of activities.
• B. Represents the detailed user tasks underneath Epics.
• C. Represents the data entities used.
• D. Represents the project timeline.

Answer: (A)

In a story map, the backbone is the high-level sequence of user activities that define the journey from start to finish. It acts as the skeleton of the map, showing the main steps a user takes, arranged in the order they occur. Detailed work items sit beneath each step as epics and user stories, giving depth to how that activity will be accomplished. The backbone isn’t about data models or a project timeline; it’s about the flow of activities the user performs. This structure helps teams discuss scope, prioritize features for an MVP, and ensure the product delivers the essential value by focusing on the core user journey.
