Project Management

Gantt Chart

A horizontal bar chart that shows project tasks against a timeline, with their durations, dependencies, and progress.

A Gantt chart displays each project task as a horizontal bar positioned along a calendar, making start dates, durations, dependencies, and overlap visible at a glance. It is the most widely used project scheduling and communication tool.

Behind a good Gantt chart sits a work breakdown structure and critical path analysis; the chart simply visualizes the schedule they define and tracks progress against the baseline.
