A Gantt chart is a visual tool used in project management to display the timeline of a project. It shows tasks or activities along a horizontal axis, with time represented on the vertical axis. Each task is represented by a bar, and the length of the bar indicates the duration of the task. This helps teams see what needs to be done, when it should be completed, and how tasks overlap. By using a Gantt chart, project managers can easily track progress and identify potential delays. It also facilitates communication among team members, as everyone can see the overall project timeline. This makes it easier to coordinate efforts and ensure that the project stays on schedule.
