A Gantt chart is a visual project management tool that illustrates a project schedule. It displays project tasks on the vertical axis and time intervals on the horizontal axis, with bars representing the duration of each task. Dependencies between tasks are often shown with connecting lines, providing a clear overview of the project timeline. In practice, Gantt charts help project managers plan, schedule, and track project progress, ensuring that tasks are completed on time and within scope. They are essential for communicating project timelines to stakeholders and identifying potential bottlenecks or delays. For example, a construction project manager might use a Gantt chart to map out the sequence of building phases from foundation laying to final inspection. Unlike a simple task list, a Gantt chart emphasizes the temporal relationships and duration of activities. This concept is fundamental to project management domains tested on the PMP, CAPM, and PMI-ACP certifications.
