A Gantt chart is a project management tool that depicts a project schedule. It is typically divided into two sections: the left side contains a list of tasks, and the right side contains a timeline with schedule bars that visualize work. The Gantt chart can also include task start and end dates, milestones, task dependencies, and assignees.

  • Allocate the resources of the project- ensure everyone knows who is responsible for what.
  • Make project adjustments – the initial plan will need many adjustments.
  • Monitor and report progress – helps you stay on schedule.
  • Control and communicate the schedule – clear visuals for stakeholders and participants.
  • Display milestones – shows key events.
