particular job arrives at the CCR. For example, if the CCR schedule
calls for this valuable resource to begin processing a particular
work order at 3:00 pm on Tuesday, the material for that job might
be released early enough to allow all preceding processing steps to
be completed at 3:00 pm on Monday (a full work day ahead of the
time required). The buffer time serves to “protect” the most
valuable resource from having no work to do—a serious failing,
since the output of this resource is equivalent to the output of the
entire system.
• It should be noted that only critical points in a service or pro­
duction process are protected by buffers. (Refer to Fig. 5.9.) These
critical points are the capacity-constrained resource, any sub-
sequent process step where assembly with other parts occurs,
and the shipping schedule. Because the pro tection against vari-
ability is concentrated only at the most critical places (and
eliminated everywhere else in the process), actual lead time can be
shortened considerably, sometimes by 50 percent or more, without
