A company runs one mobile application, and three teams work on it. Each team has drawn a product boundary around its own area and maintains its own backlog and vision. What does the material say about drawing product boundaries this way?

• AThe boundary is a property of the product, defined by its users and the value it delivers, so a boundary drawn around teams produces several backlogs for something users experience as one thing.
• BThis is correct, since each team needs its own vision to stay focused.
• CBoundaries should be drawn around technical components, since that is where ownership is clearest.
• DThe number of backlogs should match the number of stakeholder groups.
