Applied Motion Study
A Collection Method to industrial Preparedness

CHRONOCYCLEGRAPH DEVICES 77 little is known.1 Permanent results in human economy demand accurate records of fatigue co- ordinated with records of achievement, and with records of the methods by which the achievement has been secured. To find and apply the necessary measures for achievement and fatigue is primarily a task for the engineer. His training impresses him with the importance of measurement. His work makes him skilled in the use of measuring devices. Success in his profession depends chiefly upon the continued application of the most accurate meas- urement available, and this provides the incentive necessary for the maintenance of the scientific method. The engineer must secure the co-opera- tion of the educator, the psychologist, the physi- ologist and the economist before he can hope to secure complete data, and to understand the full interpretation of what he finds,— but this is his duty 1. To make the investigation in the most scien- tific manner of which he is capable. 2. To submit his finds for comparative study by others and for the use of the world. i See “Fatigue Study,” Sturgis & Walton, 31 East 27th Street, New York.
