Some University departments require students to create a Gantt chart to represent a schedule for the research project. The Gantt chart shows the timelines of the various steps of the project including their dependencies and any resources needed. In other words, the chart depicts when an event is supposed to take place in your project by providing an outline regarding the order in which the various tasks need to be performed.
