A Gantt chart is a project-management scheduling tool that displays activities along a calendar-based timeline. Each activity is typically represented by a horizontal bar beginning at its planned start date and ending at its planned completion date. This allows the project manager to visualize task duration, overlapping activities, milestones, sequencing, and overall project progress.

A work breakdown structure decomposes the total project scope into smaller deliverables and work packages. Although essential for planning, it does not primarily display work against calendar time. Critical path analysis identifies the dependent sequence of tasks that determines the shortest possible project completion time. A PERT chart is a network diagram used to analyze task dependencies and estimated durations, especially when activity timing contains uncertainty.

The defining phrase in the question is that project tasks and milestones are displayed according to beginning and end dates on a timeline. That is the fundamental structure of a Gantt chart.

Talent development professionals may use Gantt charts to manage curriculum development, technology implementations, learning launches, evaluation projects, and organizational-development initiatives involving multiple deliverables and deadlines.
