He must be proficient at the art of imparting his knowledge to other workmen, and at the same time be able to secure the prescribed outputs and quantities. He need not be the fastest worker in the shop, but he should be one of the most intelligent workers and best teachers, with a keen desire to cooeperate, both with the workers and with the other foremen. THE REPAIR BOSS.--The repair boss has charge of the plant and its maintenance. He must have a natural love of order and of cleanliness, and a systematic type of mind. This position calls for a man with an experience that will enable him to detect liability of breakdowns before they actually occur. He must be resourceful in repairing unexpected breakdowns in an emergency, and be able at all times to carry out literally the directions given on the instruction cards of the Planning Department for cleaning, maintaining, and repairing the machines. THE INSPECTOR.--The function of inspector under scientific or the Taylor plan of management is most important, especially in connection with the "first inspection." During the manufacture of the first piece and after it is finished the inspector passes and reports upon it before the worker proceeds with the other pieces. Here the worker gets a return in person for each successive act on the first piece he makes under a new instruction card, or, if he is a new worker, under an old instruction card. Ambiguity of instructions, if present, is thus eliminated, and wrong actions or results are corrected before much damage to material has been done and before much time and effort are wasted. The first erroneous cycles of work are not repeated, and the worker is promptly shown exactly how efficiently he has succeeded in determining the requirements of his instructions. The inspector is responsible for the quality of the work. He fulfills the requirements of Schloss, who says, in speaking of the danger, under some managements, that the foreman will sacrifice quality to speed, if he gets a bonus for quantity of output,--"The best safeguard against this serious danger would be found in the appointment of a distinct staff of inspectors whose duty it should be to ascertain, as the work proceeds, that the stipulated standards of excellence are at all times scrupulously maintained." This position of inspector requires an observant man who naturally is inclined to give constructive rather than destructive-criticism. He should be a man who can cooeperate with the workman and foreman to rescue condemned or damaged material with the least expenditure of time, effort and expense. FUNCTIONALIZING THE WORKER.--Under Scientific Management, the worker as well as the foreman, is a specialist. This he becomes by being relieved of everything that he is not best fitted to do, and allowed to concentrate upon doing, according to exact and scientifically derived methods, that work at which he is an expert.[13]
