Is it true that all Development Teams working on the same Product should use the same Product Backlog?

The assertion that all Development Teams working on the same Product should use the same Product Backlog is indeed true. This principle is foundational in Scrum, as it ensures that all teams are aligned and working towards the same goals and priorities. By utilizing a single Product Backlog, the Product Owner can maintain a clear and coherent vision of the product, providing transparency and enabling collaboration among the teams.

Having a unified Product Backlog promotes consistency in the prioritization of features and eliminates the risk of teams working on conflicting items or duplicating efforts. It also allows for better resource management and planning since all teams can see the same priorities and dependencies, leading to improved coordination in their work.

This collaborative approach is crucial in delivering a cohesive product that meets the intended market needs and adheres to the product vision established by the Product Owner.
