Which project documentation tool graphically displays the start date, end date, and duration of project activities?

1. Work breakdown structure

2. Gantt chart

3. PERT chart

4. Pareto diagram

The correct answer is: Gantt chart

The Gantt chart is a project management tool that visually represents the timeline of a project, including individual activities, their start dates, end dates, and durations. It is particularly useful for tracking project schedules and ensuring that tasks are completed on time. Gantt charts allow project managers to easily see which activities overlap, how long each task will take, and the overall progress of the project. This visual format helps in communicating the timeline to stakeholders and team members, aiding in effective project coordination. In contrast, the work breakdown structure serves to define and organize project tasks but does not provide a timeline or show durations. The PERT chart, while it does depict relationships and sequencing for project tasks, is more focused on identifying the minimum time needed to complete the entire project rather than showing individual task durations prominently. The Pareto diagram is a tool for identifying the most significant factors in a dataset through the 80/20 rule principle and does not relate to project scheduling or timelines. Thus, the Gantt chart stands out as the correct choice for visualizing project activities in terms of time, making it the appropriate answer to this question.
