be seen by referring to the data entered on face of
note sheet, Fig. 2 (page 151).
In this case, instead of observing, first, the “time to
fill a shovel,” and then the time to uthrow it into a
wheelbarrow,” etc., a number of these more rudimen-
tary operations are grouped into the single operation of
a = “Time filling a wheelbarrow with any mate-
rial.”
This group of operations is thus studied as a
whole.
Another illustration of the degree of subdivision
which is desirable will be found by referring to the
inserts, Fig. 5 (opposite page 166).
Where a general study is being made of the time
required to do all kinds of hand work connected with
and using machine tools, the items printed in detail
should be timed singly.
When some special job, not to be repeated many
times, is to be studied, then several elementary items
can be grouped together and studied as a whole, in
such groups for example as:
(a) Getting job ready to set.
(b) Setting work.
(c) Setting tool.
(d) Extra hand work.
(e) Removing work.
And in some cases even these groups can be further
condensed.
An illustration of the time units which it is de-
sirable to sum up and properly record and index for
a certain kind of lathe work is given in Fig. 6.
