Which statement best distinguishes a Gantt progress chart from a Gantt load chart?

A Gantt progress chart compares actual progress or output of jobs against the planned schedule, supporting control, whereas a Gantt load chart shows how much work is assigned to each machine or work centre over time, supporting loading decisions.

  1. AA progress chart compares actual output with planned output for jobs over time, while a load chart shows work assigned to resourcesCorrect
  2. BA progress chart shows machine idle time only, while a load chart shows job costs
  3. CA progress chart is used only for inventory, while a load chart is used only for quality control
  4. DThere is no difference; both show the same information in the same format

Explanation

A Gantt progress (or record) chart tracks actual performance against the plan for each job, helping control. A load chart shows the allotment of work to machines or centres. The other options assign incorrect purposes to the charts.
