A Gantt chart is a visual tool used in project management to represent the timing of tasks required to complete a project. It is particularly useful for showing the start and finish dates of elements of a project, dependencies between tasks, and the current schedule status.

justify the need and rationale for the change and its implications on the project objectives and deliverables. A
change request also helps to initiate the change control process, which involves reviewing, approving,
