Gantt chart
type of bar chart used for schedules and dependencies
A Gantt chart is a bar chart that illustrates a project schedule. It was designed and popularized by Henry Gantt c. 1910–1915. Modern Gantt charts also show the dependency relationships between activities and the current schedule status.
Definition
A Gantt chart is a type of bar chart that illustrates a project schedule. This chart lists the tasks to be performed on the vertical axis, and time intervals on the horizontal axis. The width of the horizontal bars in the graph shows the duration of each activity. Gantt charts illustrate the start and finish dates of the terminal elements and summary elements of a project. Terminal elements and summary elements constitute the work breakdown structure of the project. Modern Gantt charts also show the dependency (i.e., precedence network) relationships between activities. Gantt charts can be used to show current schedule status using percent-complete shadings and a vertical "TODAY" line.
