"Organization charts. — A chart showing clearly the line of authority and of responsibility of each individual in an organization will go far toward removing many inter-departmental jealousies. The chart should be so simple that it is self-explanatory upon inspection. Each man's position is thus made perfectly clear and he easily informs himself as to what course to take when transacting business with other departments. If applied to a factory, each workman will know to what particular gang boss or job boss he is directly responsible; each gang boss or job boss will know to what foreman he must report; and each foreman will know to what superintendent he is responsible; and each superintendent will know where his authority begins and ends with respect to other departmental heads. Further-more, the chart should show who is responsible for machines and equipment. To be most effective the chart should be hung in a conspicuous place. Each of the manufacturing departments should have one as well as the office; 24x36 inches is a suitable size. When made in the form of blue-prints charts are inexpensive, but they should be framed and protected by glass, to shield them from pencil markings and other injuries."
