FIGURE 3. -WATCH BOOK FOR TIME STUDY
[Transcriber's note -- Figure 3 omitted]
The operation selected for illustration on the note sheet shown in Fig.
2, page 151, is the excavation of earth with wheelbarrows, and the
values given are fair averages of actual contract work where the
wheelbarrow man fills his own barrow. It is obvious that similar methods
of analyzing and recording may be applied to work ranging from unloading
coal to skilled labor on fine machine tools.
The method of using the note sheets for timing a workman is as follows:
After entering the necessary descriptive matter at the top of the sheet,
divide the operation to be timed into its elementary units, and write
these units one after another under the heading "Detail Operations." If
the job is long and complicated, it may be analyzed while the timing is
going on, and the elementary units entered then instead of beforehand.
In wheelbarrow work as illustrated in the example shown on the note
sheet, the elementary units consist of "filling barrow," "starting"
(which includes throwing down shovel and lifting handles of barrow),
"wheeling full," etc. These units might have been further
subdivided--the first one into time for loading one shovelful, or still
further into the time for filling and the time for emptying each
shovelful. The letters a, b, c, etc., which are printed, are simply for
convenience in designating the elements.
