In a scenario with multiple Scrum Teams building one product, what is a crucial condition to maintain?

In a scenario where multiple Scrum Teams are collaborating to build a single product, having only one Product Backlog is crucial for several reasons. The primary function of the Product Backlog is to provide a clear and unified view of the work that needs to be done, prioritized according to the product's goals and stakeholder needs. When multiple teams draw from the same backlog, it ensures alignment across teams regarding the product vision, goals, and the delivery of features.

This unified approach helps in avoiding duplication of effort, conflicting priorities, and ensures that all teams have clarity about the most important work to be done. It also simplifies communication and coordination, as all teams are working towards a common set of items, which can lead to improved synergy and collaboration.

Furthermore, sharing a single Product Backlog fosters transparency among teams and stakeholders, as everyone can see the same set of priorities and progress, enabling better decision-making regarding the development process.

A single Product Backlog is a best practice in Scrum, particularly for complex products that require the involvement of multiple teams, as it helps maintain focus on delivering value to the customer in a cohesive manner.
