The Gantt chart is a specialized chart used for displaying various timelines like project timelines, development timelines etc. It can be used for any of the following; planning and scheduling projects, assessing how long a project should take, laying out the order in which tasks need to be carried out, managing dependencies between tasks and determining the resources needed. In short, Gantt charts help you monitor progress of a project. You can immediately see what should have been achieved at a point in time. Also they allow you to judge how remedial action may bring the project back on course, if it’s running off track.
