What best describes the Sprint Backlog?

The Sprint Backlog is best described as the Development Team Plan for the Sprint. It is an actionable, detailed plan that outlines the work the team intends to complete during the current Sprint. This plan typically includes a subset of the items from the Product Backlog that the team has committed to delivering by the end of the Sprint.

The Sprint Backlog is dynamic; it can evolve throughout the Sprint as the Development Team learns more about the work and the necessary tasks to achieve the Sprint Goal. It represents a collaborative effort where the Development Team breaks down the selected Product Backlog items into actionable tasks, thus enabling them to track their progress and manage their workload efficiently.

Understanding the essence of the Sprint Backlog, as a focused plan for the current Sprint, sets it apart from the other choices. For instance, completed project tasks do not belong in the Sprint Backlog, as it represents future work, not what has already been achieved. A compilation of all user stories is also incorrect, as the Sprint Backlog should only contain those user stories selected for the current Sprint, not all existing user stories. Lastly, a detailed long-term project timeline does not capture the flexible and iterative nature of Scrum, since the Sprint Backlog is specific to the Sprint's immediate work
