This motion study can be accurate and of permanent value only in so far as the divisions are final.
Here we note only that the task is built up of elementary units measured by motion study, time study, and micro-motion study.
Also motion study and time study determine exactly how a tool or a piece of equipment can best be used.
motion study and time study are the most efficient measuring device of the relative qualities of differing methods.
To find this "one best" method, industry has evolved a complete technique of time and motion study.
That is, measurements in general and motion study and time study in particular must become a matter of government investigation.
Much chagrined, I gave in, and called in the motion study engineers and set them to the task.
There is little so unimportant that time and motion study would not be valuable.
