The Product Backlog should be prioritized based on business importance and the value it delivers to the stakeholders. This means that the items with the highest business value or return on investment (ROI) should be at the top of the backlog. Prioritizing the backlog in this way ensures that the team is focused on delivering the most important features first, which can help to maximize the value of the product.

The Product Owner is responsible for prioritizing the Product Backlog and ensuring that it is transparent to the entire Scrum Team. They should work closely with stakeholders to understand their needs and priorities and use this information to prioritize the backlog. By prioritizing the backlog in this way, the team can focus on delivering the most valuable features first, which can help to increase customer satisfaction and generate a higher return on investment for the organization.

If the Definition of Done for an increment is part of the standards of the organization, all Scrum Teams must follow it as a minimum. If it is not an organizational standard, the Scrum Team must create a Definition of Done appropriate for the product.

The Developers are required to conform to the Definition of Done. If there are multiple Scrum Teams working together on a product, they must mutually define and comply with the same Definition of Done.

We don't baseline any artifact in Scrum. The Sprint Backlog is dynamic and changes during the Sprint to include newly identified tasks.

Multiple Scrum Teams often work together on the same product. One Product Backlog is used to describe the upcoming work on the product.

Scrum is a process framework that has been used to manage work on complex products since the early 1990s. Scrum is not a process, technique, or definitive method. Rather, it is a framework within which you can employ various processes and techniques. Scrum makes clear the relative efficacy of your product management and work techniques so that you can continuously improve the product, the team, and the working environment.

The Sprint Backlog is a living artifact and the scope may be clarified and re-negotiated between the Product Owner and the Developers as more is learned. A Sprint Backlog is flexible, as long as changes do not distract from the focus on the Sprint Goal.

In Agile projects, the customer is kept satisfied by delivering a valuable product continuously. Agile methodology emphasizes on delivering working software or product in small increments.

A single product should have a single Product Backlog and hence the only one owner, a Product Owner. A P.O. can delegate some of his responsibilities to the team, however they are still accountable for Product Backlog ownership.

- The Product Backlog is an emergent, ordered list of what is needed to improve the product. Attributes often vary with the domain of work.

- The Sprint Backlog is updated throughout the Sprint as more is learned.

- Composition of the Scrum Team can be changed during the Sprint if needed but it's not best practice.

- The Sprint Goal never changes during the Sprint.
