User Story Mapping

User Stories: What Does the User Really Need?

• A user story captures a feature that delivers real value to the user
• It represents a small, user-focused piece of functionality
• Helps developers see the system from the user's point of view

Stories can be grouped and structured using User Story Mapping

What is User Story Mapping?

• A visual method to organize user stories
• Shows the user journey as a series of activities and tasks
• Helps teams understand needs and prioritize features
• Reflects the user’s workflow in a clear, time-ordered way
• Encourages shared understanding among team members

Step 1: Identify Activities

What is an Activity?

• A meaningful goal-oriented action performed by the user
• Represents a high-level step in the user journey
• In user story mapping:
  → Appears as a top-level horizontal row

One activity = several related user stories

Activities vs Related Terms

How to Identify Activities

1. Understand the user's goal
2. Describe the user's action scenario
3. Break it into meaningful steps
4. Arrange steps in time order
5. Adjust the granularity for planning and release

Example: Tic-Tac-Toe

User goal: Play and enjoy the game

Activities:

• Start a new game
• Place a mark
• Check win/loss
• Display the result
• Restart the game

Common Mistakes: What Activities Are Not

Step 2: Write User Stories

What is a User Story?

• A short, clear description of what the user wants
• Written from the user’s perspective
• Explains what the user wants to do and why it matters
• Guides development with a focus on user value
• Small enough to be developed and tested quickly

User Story Template

• Format:
  "As a [user], I want to [do something], so that [achieve value]."

• Focus on:

  • Who is the user?
  • What do they want to do?
  • Why is it important?

Example:
“There is a problem, so enabling what leads to customer value.”
「Who が What をできるようにする。Problem という課題があり、What をできるようにすることで、Customer Value が得られる」

Example Stories

Activity: Place a Mark

As a player, I want to place a mark (○ or ×) on the board, so that I can take my turn in the game.

Activity: Judge Result

As a player, I want the game to determine if I have won or lost, so that I can know the outcome.

Step 3: Arrange User Stories

How to Organize User Stories

• Place user stories in horizontal rows under each activity
• The top row shows key activities (user goals)
• The second row shows related user stories
• The third row (optional) shows technical tasks or sub-tasks
• This layout helps visualize the user journey and workflow

Example: Tic-Tac-Toe User Story Map

This map helps teams see what the user does, what features they need, and what tasks must be built.

Step 4: Prioritize and Release

How to Prioritize User Stories

• Focus on stories that are critical for the user experience
• Consider dependencies between stories
• Group stories into releases based on value and dependencies
• Each release should deliver a meaningful outcome to the user

Example: Tic-Tac-Toe Releases

You don’t always need to follow story order.
For example: US1 + US2 + US4 can be released together if they have no dependencies.

Summary

• User story mapping is a powerful way to visualize user needs and plan development.
• It helps teams understand the user journey and structure stories around real goals.
• By identifying activities, writing user stories, arranging them, and planning releases,
  teams can build software that delivers real value to users.
