Gant and Pert charts

Gantt chart

A visual representation of a project schedule showing activities and the time required to complete each.

Main uses of a Gantt chart

To list project activities, estimate time for each, and track progress against the schedule.

Adjusting project resources with a Gantt chart

Shift workers to other projects if ahead of schedule or add workers if behind schedule.

PERT chart

A graphical representation of a project's tasks, their sequence, and the critical path for project completion.

Critical path in a PERT chart

The longest stretch of dependent activities that determines the minimum time needed to complete the project.

Difference between PERT and Gantt charts

PERT charts emphasize task dependencies and critical paths, while Gantt charts focus on individual task timelines.

Importance of identifying the critical path

Delays in critical path activities will directly impact the project's completion deadline.
