wander. This, under
Scientific Management, is constantly furnished by the collection of
jobs ahead on the bulletin board. The tasks piled up ahead upon this
bulletin board provide a needed and ready change for the subject of
attention or interest, which conserves the economic value of
concentrated attention of the worker upon his work. Such future
tasks furnish sufficient range of subject for wandering attention to
rest the mind from the wearying effect of overconcentration or
forced attention. The assigned task of the future systematizes the
"stream of attention," and an orderly scheme of habits of thought is
installed. When the scheme is an orderly shifting of attention, the
mind is doing its best work, for, while the standardized extreme
subdivision of Taylor's plan, the comparison of the ultimate unit,
and groupings of units of future tasks are often helps in achieving
the present tasks, without such a definite orderly scheme for
shifting the attention and interest, the attention will shift to
useless subjects, and the result will be scattered.

INCENTIVES MAINTAIN INTEREST.--The knowledge that a prompt
reward will follow success stimulates interest. The knowledge that
this reward is sure concentrates attention and thus maintains
interest.

In the same way, the assurance of promotion, and the fact that
the worker sees those of his own trade promoted, and knows it is to
the advantage of the management, as well as to his advantage, that
he also be promoted,--this also maintains interest in the work.

THIS INTEREST EXTENDS TO THE WORK OF OTHERS.--The interest is
extended to the work of others, not only by the interrelated
bonuses, but also by the fact that every man is expected to train up
a man to take his place, before he is promoted.

CLOSE RELATIONSHIP OF ALL PARTS OF SCIENTIFIC MANAGEMENT HOLDS
INTEREST.--The attention of the entire organization, as well as of
the individual worker, is held by Scientific Management and its
teaching, because all parts of Scientific Management are related,
and because Scientific Management provides for scientifically
directed progression. Every member of the organization knows that
the standards which are taught by Scientific Management contain the
permanent elements of past successes, and provide for such
development as will assure progress and success in the future. Every
member of the organization realizes that upon his individual
cooeperation depends, in p
