ues to remain competitive against other countries. Motion study analyzed every detailed in the operation to perform a particular task and determined the method which used the least amount of energy. An example of this research is the assembly of piece used in the production of the braider manufactured by the New England Butt Company (Gilberth 1917). After analysis using motion study there was a three hundred and fifty percent increase in production with no increase in worker fatigue (Gilbreth 1917). The analysis consisted of what is the unit of measure, the difference methods used, and devices needed. All three are needed to be incorporated to obtain a result.The use of chronocyclegraph motion devices was another method used in motion study. Chronocyclegraph devices were used in the study to formulate a precise scientific conclusion to an investigation. Clocks, temperature, and location devices was used during the study. This was necessary to get the accurate time of day, temperature, and place a study was performed. The information can be reference in the future or the present by scientist and scholars to compare other scientific results from motion study. The third type used to reach a conclusion in motion study was a motion model. Motion models were used mainly in educational sector (Spriegel 1953). It dealt with the different methods of teaching by an individual. The synopsis of the study was that different methods are used to perform the task than what is taught by the teacher. In one example, the teacher taught a person who was unfamiliar with a subject a very thorough explanation on how to accomplish the task, which was very time consuming (Gilbreth 1917). On the other hand, when actually performing the task the instructor used shortcuts that reduced the amount of time to perform the task (Gilbreth 1917).Another of the Gilbreths works was a study of fatigue in the workplace Fatigue is the weariness from labor or exertion (Webster...
