User story mapping is becoming a popular technique through the efforts of Jeff Patton and others that allows you to add a second dimension to your backlog. Here are a few reasons you should consider using this technique:
- It allows you to see the big picture in your backlog.
- It gives you a better tool for making decisions about grooming and prioritizing your backlog.
- It promotes silent brainstorming and a collaborative approach to generating your user stories.
- It encourages an iterative development approach where your early deliveries validate your architecture and solution.
- It is a great visual alternative to traditional project plans.
- It is a useful model for discussing and managing scope.
- Allows you to visualize dimensional planning and real options for your project/product.
