Which project management artifact is used to visualize the sequence and timing of activities?

• A. Gantt Chart
• B. Scatter diagram
• C. Network diagram
• D. Histogram

Answer: (A)

Visualizing the sequence and timing of activities is all about showing when each task starts, how long it lasts, and how tasks overlap on the timeline. A Gantt chart does exactly that: each activity is shown as a horizontal bar along a time axis, with the bar’s start and end dates reflecting the schedule and the bar length representing duration. This layout makes it easy to see the order of activities, which tasks run concurrently, and whether the plan is on track by comparing planned versus actual progress.

Other options serve different purposes. A network diagram emphasizes the logical relationships and dependencies between activities, outlining which tasks must precede others but not presenting a clear calendar view of timing. A scatter diagram and a histogram are used for data analysis and quality metrics, not for displaying a project schedule.
