2. ability to assign men to the work which they should do, to prescribe the method which they shall use, and to reward them for their output suitably;
3. ability to predict. On this ability to predict rests the possibility of making calendars, chronological charts and schedules, and of planning determining sequence of events, etc., which will be discussed at length later.
Ability to predict allows the managers to state "premature truths," which the records show to be truths when the work has been done.
It must not be forgotten that the managers are enabled not only to predict what the men, equipment, machinery, etc., will do, but what they can do themselves.
The Effect on the Men Is That the Worker Co-operates. — 1. The worker's interest is held. The men know that the methods they are using are the best. The exact measurements of efficiency of the learner, — and under Scientific Management a man never ceases to be a learner, — give him a continued interest in his work. It is impossible to hold the attention of the intelligent worker to a method or process
that he does not believe to> be the most efficient and least wasteful.
Motion study and time study are the most efficient measuring device of the relative qualities of differing methods. They furnish definite and exact proof to the worker as to the excellence of the method that he is told to use. When he is convinced, lack of interest due to his doubts and dissatisfaction is removed.
2. The worker's judgment is appealed to. The method that he uses is the outcome of coöperation between him and the management. His own judgment assures him that it is the best, up to that time, that they, working together, have been able to discover.
3. The worker's reasoning powers are developed. Continuous judging of records of efficiency develops high class, well developed reasoning powers.
5. There is elimination of soldiering, both natural and systematic.[20]
