The forcefulness of the "don't" and the "never" have been investigated by education. Undoubtedly the "do" is far stronger, but in this particular case the command deduced from the records of delay to others is, necessarily, in the negative form, and a study of the psychological results proves most instructive. BENEFITS TO MANAGERS OF INDIVIDUAL RECORDS.--The value of the training to the foremen, to the superintendents and to the managers higher up, who study these records, as well as to the timekeepers, recorders and clerks in the Time and Cost Department who make the records, is obvious. There is not only the possibility of appreciating and rewarding the worker, and thus stimulating him to further activity, there is also, especially in the Transitory stage, when men are to be chosen on whom to make Time Study observations, an excellent chance to compare various methods of doing work and their results. INCENTIVES WITH INDIVIDUAL RECORDS.--The greatest value of recorded outputs is in the appreciation of the work of the individual that becomes possible. First of all, appreciation by the management, which to the worker must be the most important of all, as it means to him a greater chance for promotion and for more pay. This promotion and additional pay are amply provided for by Scientific Management, as will be shown later in discussing Incentives and Welfare. Not only is the work appreciated by the management and by the man himself, but also the work becomes possible of appreciation by others. The form of the record as used in Scientific Management, and as introduced early in the transitory stage, makes it possible for many beside those working on the job, if they take the pains to consult the records, which are best posted in a conspicuous place on the work, to know and appreciate what the worker is doing. This can be best illustrated, perhaps, by various methods of recording output on contracting work,--out-of-door work. The flag flown by the successful contestants in the athletic contests, showing which gang or which individual has made the largest output during the day previous, allows everyone who passes to appreciate the attainment of that particular worker, or that group of workers. The photographs of the "high priced men," copies of which may be given to the workers themselves, allow the worker to carry home a record and thus impress his family with what he has done. Too often the family is unable by themselves to understand the value of the worker's work, or to appreciate the effect of his home life, food, and rest conditions upon his life work, and this entire strong element of interest of the worker's family in his work is often lost.
