How do you create a Gantt Chart?

A Gantt chart represents activities as horizontal bars displayed beneath a time scale, with the name of the activity in a list on the left. Each bar shows when an activity will begin and end. Henry Gantt invented the charts that bear his name in 1910, creating them by hand using drawing tools and poster board.

These days, Gantt charts are created using project management software, such as Microsoft Project or Open Workbench, based on a work breakdown structure and project schedule. Many modern software tools also represent dependencies among tasks, borrowed from the PERT chart.
