Which term describes the estimation of project time through a Gantt chart?

The term that best describes the estimation of project time through a Gantt chart is task duration. A Gantt chart is a visual representation of a project schedule, displaying tasks along a timeline. Each task is represented by a horizontal bar, where the length of the bar corresponds to the duration of that task. This allows for easy visualization of start and end dates, the overall timeline of the project, and how tasks overlap or relate to one another in terms of time.

In project management, understanding task duration is critical for planning resources, setting deadlines, and monitoring progress. By breaking down the project into specific tasks and estimating how long each will take, a Gantt chart helps project managers achieve effective time management and ensure that the project stays on track.
