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: 

    1.  Determining the capabilities of the boy, that is, seeing
       what he is, by nature and training, best fitted to do.
    2.  Determining the possibilities of his securing work in the
       line where he is best fitted to work, that is, studying
       the industrial opportunities that offer, and the “welfare”
       of the worker under each, using the word welfare in the
       broadest sense, of general wellbeing, mental, physical,
       moral and financial.

WORK OF ACADEMIC WORLD.—­The Academic World is also, wherever it is progressive, attempting to study the student, and to develop him so that he can be the most efficient individual.  Progressive educators realize that schools and colleges must stand or fall, as efficient, as the men they train become successful or unsuccessful in their vocations, as well as in their personal culture.
