Gantt Chart

A Gantt chart is a popular type of bar chart that illustrates the start and finish dates of the project activities.A common criticism is that Gantt charts communicate relatively little information per unit area of display. A Gantt chart focus primarily on schedule management so it does not represent the size of a project or the relative size of work elements, therefore the magnitude of a behind-schedule condition is easily misinterpreted. A related criticism is that all activities of a Gantt chart show planned workload as constant. In practice, many activities have front-loaded or back-loaded work plans.
