Which chart can best represent a project team's progress and velocity over time?

In assessing a project team's progress and velocity over time, a Gantt chart stands out as the most effective choice. A Gantt chart provides a visual timeline of project activities, displaying the start and end dates of tasks, which allows stakeholders to easily track progress against the schedule. It illustrates the dependencies between tasks and shows how work is progressing, enabling teams to adapt and manage resources effectively throughout the project lifecycle.

The clarity of a Gantt chart helps project managers identify if the team is on track to meet deadlines and maintain velocity, as it visually represents work completed versus work remaining. This makes it a powerful tool for monitoring overall project progress and facilitating discussions about any necessary adjustments to the project plan.

Other options such as control charts, histograms, and fishbone diagrams serve different purposes. Control charts are used primarily for monitoring process variability over time, histograms provide a graphical representation of data distribution, and fishbone diagrams are utilized for root cause analysis. None of these tools are primarily focused on illustrating project progress and velocity in the same way a Gantt chart does.
