During a Sprint, what does the Scrum Team use to clarify and potentially re-negotiate the scope?

The correct choice is based on the understanding that the Scrum Team relies on the Product Backlog as a dynamic and prioritized list that outlines the work needed to achieve the product's goals. During a Sprint, if there is a need to clarify or re-negotiate the scope, the Product Backlog items provide the team with a clear set of definitions, priorities, and acceptance criteria that guide what should be delivered.

As new information emerges during the Sprint and the team gains a better understanding of what can be accomplished within the Sprint time frame, they can refer back to the Product Backlog to adjust their current focus. This ensures that the team remains aligned with stakeholder expectations and maximizes the value delivered.

Other options, while relevant in their own contexts, do not serve the specific purpose of clarifying and negotiating scope within the Sprint. Completed work reflects what has already been achieved rather than what remains to be defined or negotiated. Previous Sprint Goals provide historical context but do not directly aid in clarifying current scope. Daily Standups promote communication and synchronization within the team, but they are not explicitly focused on renegotiating the scope of work. Therefore, the Product Backlog is the most appropriate tool for the task at hand.
