Gantt chart is a business tool that helps project managers and other professionals to track the progress of their projects. Gantt charts are typically drawn with a bar chart that represents the tasks, and each task is assigned a time frame. The Gantt chart can also be drawn as an outline view with tasks on the left side and resources on the right side. The timeline can help to identify which tasks will take longer than others, as well as when they need to be completed so that everything is completed on time.
