APPLIED MOTION STUDY
will no longer warrant further study, or the avail-
able appropriation of time or money is exhausted.
The most efficient motions, as determined by the
tests of motion-study and time-study are then syn-
thesised into a method of least waste.
This outline of the steps in taking motion-study
and time study is necessarily incomplete, lack-
ing, as it does, discussion of the selection of the
observer, the observed worker, and many other
elements of scientific management.
As for the particular device by which the meas-
urements are made, the choice depends mainly on
the equipment available. Standards have been
improved even by merely timing the work by
counting, where no timing devices were at hand.
Excellent work had been done with stop watches.
But we advocate the use of micromotion-study in
all work demanding precision. Micromotion-
study consists of recording the speed simultan-
eously with a two or three dimensional path of
motions by the aid of cinematograph pictures of
a worker at work and a specially designed clock
that shows divisions of time so minute as to indi-
cate a different time of day in each picture in the
cinematograph film. Through micromotion-study
