Todd Olmstead is the Meals-on-Wheels dispatcher for the Atlanta metropolitan area. He wants meals delivered to clients within 30 minutes of leaving the kitchens. Meals with longer delivery times tend to be too cold when they arrive. Each of his 10 volunteer drivers is responsible for delivering 15 meals daily. Over the past month, Todd has recorded the percentage of each day’s 150 meals that were delivered on-time.
