The project manager should consult a Gantt chart after the sponsor states that the project is taking too long to
complete. A Gantt chart is a graphical tool that shows the schedule of a project, including the start and end
dates, durations, dependencies, milestones, and progress of each task or activity. A Gantt chart can help to
monitor and control the project timeline and identify any delays, variances, or issues that may affect the
project completion.
