VARIABLES OF THE MOTION
85
The list of variables here given makes no claim to being
complete. The field of study is so immense that it is im-
possible as yet to give a complete and detailed method of
attack.
It will be noted in reading the discussion of the vari-
ables that it has been found extremely difficult to handle
each one separately. It is needless to tell the student, the
investigator, the cost-reducing manager, that, difficult as
the task is, for the best results each variable must be
studied alone. The effects of all variables but one must
be eliminated, or, better perhaps, all variables but one
must be maintained constant.
Quicker results may often be obtained by studying
several variables simultaneously, and for short jobs this
may be advisable. But for long jobs of repetitive work
there is no way so accurate and satisfactory as studying
one variable at a time.
