be greatly reduced. The quality of the output
cannot be made the preliminary standard, since
this would allow of unstandardised motions, with
an ensuing decrease of speed, and would result
in unstandardised times.
2. The chronocyclegraph shows plainly the ef-
fects of habit. We have convincing illustrations
of loss in efficiency due to the intrusion of old
habits. They show that a discarded habit will
return and obtrude itself when a new method is
for some reason insisted upon, and the existing
habit cycle is broken down in order that the new
one may be formed. Say, the worker used orig-
inally habit A, and has come to use habit B. If
he be taught cycle C, which differs from A and
B, where he fails in C, he will be apt to intro-
duce an element from A, not from B. The com-
plication is evident. To profit by habit the laws
of habit formation must be rigidly utilised.1
These laws support the dictum, “ Right motions
first.”
