"The achievement of Gantt offers a means of measuring the human or social efficiency of industry... Gantt's method has made it possible to ascertain the cause of the diseased industry just as blood analysis established the cause of malaria. While the latter made the completion of the Panama Canal possible, the former will transform industry from servitude into creative service and its pensioners into respectable members of the community... Unlike statistical diagrams, curve records, and similar static forms of presenting facts of the past (Gantt) charts... are kinetic, moving, and project through time the integral elements of service rendered in the past toward the goal in the future."
