What is a backlog in project management and how does it impact the overall progress and success of a project?

In project management, a backlog is a list of tasks or work items that need to be completed. It can include new features, bug fixes, or other project-related tasks. A backlog can impact the overall progress and success of a project by causing delays, inefficiencies, and confusion if not managed properly. It can lead to missed deadlines, increased costs, and decreased stakeholder satisfaction. Prioritizing and managing the backlog effectively is crucial for keeping a project on track and achieving its goals.
