A Gantt chart is a horizontal bar chart developed as a production control tool in 1917 by Henry L. Gantt, an American engineer and social scientist. Frequently used in project management, a Gantt chart provides a graphical illustration of a schedule that helps to plan, coordinate, and track specific tasks in a project.Gantt chart is a project planning tool that graphically displays activities of a project in sequential order and plots them against time.
A typical Gantt chart graphically displays the work breakdown, total duration needed to complete tasks, as well as percentage of completion. The Gantt chart itself will not display level of effort, and is not an effective planning tool on its own. Today, Gantt Charts may be integrated with other spreadsheet-type reporting devices that convey additional information related to project planning.
