INDIVIDUALITY CONSIDERED IN SELECTING WORKERS.--Under Scientific Management individuality is considered in selecting workers as it could not be under either of the other two forms of management. This for several reasons: 1. The work is more specialized, hence requires more carefully selected men. 2. With standardized methods comes a knowledge to the managers of the qualifications of the "standard men" who can best do the work and continuously thrive. 3. Motion study, in its investigation of the worker, supplies a list of variations in workers that can be utilized in selecting men.[8] VARIABLES OF THE WORKER.--This list now includes at least 50 or 60 variables, and shows the possible elements which may demand consideration. When it is remembered that the individual selected may need a large or small proportion of most of the variables in order to do his particular work most successfully, and that every single one of these variables, as related to the others, may, in some way affect his output and his welfare in doing his assigned work, the importance of taking account of individuality in selection is apparent. SCIENTIFIC MANAGEMENT NEEDS SUPPORT IN STUDYING WORKERS.--The best of management is by no means at its ultimate stage in practice in this field. This, not because of a lack in the laws of management, but because, so far, Scientific Management has not received proper support from other lines of activity. PRESENT LACK OF KNOWLEDGE OF APPLICANTS.--At present, the men who apply to the Industries for positions have no scientifically determined idea of their own capabilities, neither has there been any effort in the training or experience of most of those who apply for work for the first time to show them how fit they really are to do the work which they wish to do. SUPPLEMENTS DEMANDED BY SCIENTIFIC MANAGEMENT.--Before the worker can be scientifically selected so that his individuality can be appreciated, Scientific Management must be supplemented in two ways:-- 1. By psychological and physiological study of workers under it. By such study of the effect of various kinds of standardized work upon the mind and body, standard requirements for men who desire to do the work can be made. 2. By scientific study of the worker made before he comes into the Industries, the results of which shall show his capabilities and possibilities.[9] WHENCE THIS HELP MUST COME.--This study must be made a. In the Vocational Guidance Work. b. In the Academic Work, and in both fields psychological and physiological investigations are called for. WORK OF VOCATIONAL GUIDANCE BUREAUS.--Vocational Guidance Bureaus are, at present, doing a wonderful work in their line. This work divides itself into two parts:
