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.
What is a Gantt Chart?
Gantt chart is a visual view of tasks/activities scheduled over time. Gantt charts are used for planning projects of all sizes and they are a useful way of showing what work is scheduled to be done on a specific day. They also help you view the start & end dates of a project in a simple view.

Why use a Gantt chart?
A Gantt chart is used for the following activities:
- Establish the initial project time schedule – who is going to do what, when and how long will it take.
- 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.
- Identify and report problems – As everything is depicted visually you can immediately see what should have been achieved by a certain date and, if the project is behind schedule, you can take action to bring it back on course.
