Applied Motion Study
A Collection Method to industrial Preparedness

AS AN INDUSTRIAL OPPORTUNITY 45 improvement and cheapening of the devices, it is now possible to make accurate records of mo- tions, even when no great outlay for the study can be afforded. The micro-motion method of making motion studies consists of recording motions by means of a motion picture camera, a clock that will record different times of day in each picture of a mo- tion picture film, a cross-sectioned background, and other devices for assisting in measuring the relative efficiency and wastefulness of motions. Suppose the process of assembly before cited is being micro-motion studied: The assembler is placed before the cross-sectioned background; the micro-motion clock is placed where it will record in the picture, yet not disturb the worker; near it is another clock which serves as a check on the accuracy of the special clock. The assembler, who has been rated a skilled worker under the old method, naturally does the best work possi- ble, since a permanent record is being made of his performance. The observer operates the mo- tion picture camera, which, however, allows him freedom to observe the assembly process continu- ally, and to note possibilities for improvement.
