It is not generally recognized that ultimate standards can best be derived in the research room and laboratory. The standard practice in the plant will be the result of the laboratory practice. If the finer measurements are made in the shop during the general working operations, much time will be lost, as shop conditions cannot be controlled as laboratory conditions can. It has been said that laboratory experimentation is not directly available in shop practice, because laboratory conditions differ from shop conditions. They certainly do differ, but so do the ultimate shop conditions that must be introduced with the new standard method. The ultimate conditions in the shop are far nearer the laboratory conditions than are the shop conditions prior to installation of the new methods. Former Method of Assembly. The method of assembly in use before the motion study and fatigue study were applied was as follows: The base of the braider was placed on an ordinary low bench, and the various parts were kept in tote boxes or on the floor. The worker selected such parts as he wished, and put the braider together according to any traditional method that he had learned, together with such changes as his whims dictated. How the New Practice was Derived. All of the previous assembly methods had been determined by the usual practice of putting braider parts _together_. In the present case the braider was taken apart; that is, handled in the reverse order of assembly, in order to determine from a new viewpoint the best method of putting the various parts together. The parts were laid out on a table in the sequence in which they were disassembled. This allowed the various members of the braider divisions, groups, and sub-groups to be studied in relation to one another and also separately. The Two Factors to Be Considered. The problem resolved itself into two parts: 1. To make the table of the most convenient height and shape to hold tools and the base group as it grew, while being assembled. 2. To provide the most convenient, temporary, resting place for the tools and the various parts, before they were carried to the final position of assembly. The two parts were so closely related that any modification in one demanded a modification in the other.

The obvious sequence in our packet method eliminates the delay and fatigue of the decision of choice.] [Illustration: FIG. 26
