Step-by-step explanation:
The Scrum Backlog is a) a list of things which the Scrum Team might do in the future. It functions as a dynamic to-do list for the team and is continuously updated. The backlog includes high-level requirements, user stories, and sometimes bugs which need to be addressed within the project. This list is prioritized based on the value each item brings to the overall project, and it is used during Sprint Planning meetings to determine which items will be handled in the next sprint.
Unlike a list of items that are behind schedule or a list of project milestones, the Scrum Backlog is focused on what the team might work on, not solely on what is delayed or the major events in the timeline of the project. The Sprint Backlog, on the other hand, is a subset of the Scrum Backlog and includes action items to be sorted out in a given sprint.
