What is a project backlog and how does it contribute to the success of a project?

A project backlog is a prioritized list of tasks or requirements that need to be completed in a project. It helps in organizing and planning the work to be done, ensuring that the most important tasks are completed first. By maintaining a project backlog, teams can stay focused, track progress, and adapt to changes efficiently, ultimately contributing to the success of the project by ensuring that goals are met in a timely and organized manner.
