Functions may be subdivided as far as the nature of the work demands. Note here, again, that it is the relative complexity or simplicity of the nature of the work that is to be done that determines the degree

of its functionalization, not the number of men employed at the work.

Note, also, that with every subdivision of functions comes greater opportunity for specialization, hence for individual development.

Place of Operation of the Functions. — Four functions of the eight find their place in the planning department. The other four are out on the work. That is to say, — the men who represent four functions work almost entirely in the planning room, while the men who represent the other four functions work mostly among the workers. This division is, however, largely a matter of convenience. Three of the first four groups of men communicate with the workers mostly in writing and are seldom engaged as observers, except in obtaining data for the creation of standards, while the fourth is often in the planning room. The last four usually communicate with the men orally, and must observe and teach the worker constantly.

In the descriptions that follow, each function is represented as embodied in one man, this aiding simplicity and clearness in description.

The Order of Work and Route Clerk. — The Order of Work and Route Clerk lays out the exact path of each piece of work, and determines the sequence of events of moving and a general outline of performance. [12] With the requirements of the work in mind, the most efficient day's work for each worker is determined. The paths and sequences of transportation

are outlined by means of route charts and route sheets showing graphical and detailed directions, which are the means by which the foremen of the other functions are enabled to coöperate with other foremen and with the workers.

The work of this function requires a practical man, of the successful foreman type, experienced in the class of work to be executed, who is also familiar with the theories of Scientific Management in general, and the work of the other foremen in particular, and who has the faculty of visualization and well developed constructive imagination. He must also have at his command in systematic form, and available for immediate use, records of previous experience.

The Instruction Card Clerk. — The Instruction Card Clerk prepares written directions for the workers as to what methods should be used in doing the work, the sequence of performance of the elements of the method, the speeds and action of the accompanying machinery, the time that each element should take for its performance, the time allowed for rest for overcoming fatigue caused by its performance, and the total elapsed time allowed for performing all of the work on the instruction card in order to obtain the unusually high additional wages as a reward for his skill and coöperation.

The work of this function requires the best available (but not necessarily the fastest), practical experienced man in the trade described, who also has had sufficient experience in motion study and time study to enable him to write down the best known method for doing the work described, and also
