Which chart is useful for displaying the schedule and status of a project over time?

A Gantt chart is specifically designed to display the schedule and status of a project over time, making it an invaluable tool for project management. It visually represents tasks or activities along a timeline, showing when each task is scheduled to start and finish. This allows project managers and team members to see how tasks are organized, identify overlaps, and track progress against deadlines.

Gantt charts also often include milestones, which denote significant points in the project timeline, further helping stakeholders understand key deliverables and deadlines. Their clear visual layout facilitates communication among team members and stakeholders about the project's status.

In contrast, while flowcharts, PERT charts, and timeline charts each have their unique uses in project planning and analysis, they do not provide the same detailed schedule and status tracking over time that Gantt charts do. Flowcharts are more focused on processes and workflows, PERT charts emphasize tasks and their dependencies for time estimation, and timeline charts often show events in sequence but lack the specific depth of task scheduling that Gantt charts provide.
