While creating a Gantt chart you need to think about all the aspects of the project that can help you understand whether the prepared schedule is workable or not, whether the right resource has been assigned to each task, what can be the potential risks before you push the project to start, etc. They are also helpful to define and manage task dependencies. It is used for planning and scheduling the project and helps you have information about the project duration, resources, and order of task completion. The left (vertical) of the chart shows the list of tasks and the adjacent (horizontal) top is the time scale. Basically, it’s a type of bar chart that is a horizontal representation of the project schedule.
