In Agile methodology, what do teams primarily use to track project progress?

In Agile methodology, teams primarily use burndown charts to track project progress. Burndown charts are essential tools that visually represent the amount of work remaining in a project over time. This allows teams to see how quickly they are completing tasks within a sprint or iteration. The purpose of a burndown chart is to provide a clear and immediate understanding of whether the team is on track to complete the work planned for that period. By visualizing the progress, teams can make necessary adjustments if they are falling behind schedule, thus facilitating better project management in an Agile environment.

Other methods such as Gantt charts, critical path analysis, and milestone documents, while useful in traditional project management practices, do not align with the iterative and flexible nature of Agile methodologies. Gantt charts are more suited for linear project planning, critical path analysis focuses on identifying the longest sequence of dependent tasks which is not typically emphasized in Agile, and milestone documents tend to document specific project phases rather than continuously track progress throughout the Agile sprints. Each of these alternatives lacks the real-time adaptability and visibility that burndown charts provide, making the latter the preferred choice in Agile project tracking.
