Gantt chart can act as performance evaluator for the project
The basic purpose of Gantt chart is that it illustrates the schedule of a project. It means that through a Gantt chart one clearly knows when the project started and how much progress the project has over a certain period of time.
One can have complete feasibility of the project with the help of Gantt chart and one clearly knows how much time, effort and money is required for the completion of project. Thus Gantt chart can act as a performance evaluator for the project.
