Which chart is commonly used to monitor production progress by comparing the production schedule with actual progress?

• A. Gantt chart
• B. PERT chart
• C. Control chart
• D. Kanban board

Answer: (A)

Tracking production progress by comparing the planned schedule to what has actually happened is best done with a Gantt chart. It lays out each task as a horizontal bar across a calendar, showing the planned start and finish dates, and it can display actual progress against those bars (for example, by shading the portion completed or marking current status). This side-by-side visualization makes delays easy to spot, shows how far each task is behind or ahead, and helps gauge overall schedule health at a glance. Some other charts serve different purposes: PERT charts focus on task dependencies and duration estimates rather than ongoing progress against a baseline; control charts monitor process quality and variation; Kanban boards illustrate workflow and work-in-progress, not time-based schedule adherence.
