Abstract
The object of the studies conducted under this project was to investigate, examine and explain the use of some of the predetermined motion time systems that have evolved during the past fifteen years. Particular attention was to be paid to two systems, Work-Factor and Methods-Time Measurement, which have achieved considerable industrial application. The time values assigned to the basic arm motions in the ·two systems were to be compared in a search for the true basic times for human motions. If the values were different, practical research was to be made into the short motion times of Methods-Time Measurement, some of which were known to be extrapolated and tentative.
