The Psychology of Management by Lillian Moller Gilbreth

(a) Habits of attention. Under Scientific Management, as we have shown, attention must become a habit. Only when it does become a habit, can the work required be properly performed, and the reward received. As only those who show themselves capable of really receiving the reward are considered to be properly placed, ultimately all who remain at work under Scientific Management must attain this habit of attention. (b) Habit of method of attack. This not only enables the worker to do the things that he is assigned satisfactorily, but also has the broadening effect of teaching him how to do other things, i.e., showing him the "how" of doing things, and giving him standards which are the outcome of mental habits, and by which he learns to measure.
