Advantages of Using a Gantt Chart:

  • Easy to understand.

  • Very easy to change the chart.
  • Can be constructed with minimal data.
  • Shows task progress vs date.

Disadvantages of a Gantt Chart:

  • Does NOT show interdependence of activities.
  • The effects of starting a task earlier or later are not shown.
  • No way to indicate variations in expected time to completion.
  • No details of a task are listed.
  • Cannot be used for predictive analysis.

Works well with a Project Responsibility Matrix. Less complex than a CPM (Critical Path Method) or a PERT chart.
