defects, and marked each defective part. The inspector compared
the total number of rejected parts to a standard to determine
whether the lot passed or failed the incoming inspection. If too
many of the purchased parts of a particular lot were determined
to be defective, the inspector placed the failed lot in quaran-
tine.21 If the purchased parts passed inspection, B&L Ireland's
materials management department stored the parts in inventory
until they were needed for assembly.
At B&L Hong Kong, the incoming inspection was performed by
each operator who was trained and responsible for checking the
parts prior to assembling them to ensure that they were of
acceptable quality for assembly. If the operator found any
defects, he or she was to ask the storekeeper to exchange the
defective parts for nondefective parts. The storekeeper, who was
also trained to perform quality inspections, verified whether
those parts submitted by the operator were in fact defective. If
they were defective, the storekeeper replaced them; if they were
not defective, the storekeeper returned them to the operator for
assembly. B&L Hong Kong employed an individual to repair repair-
able defective parts so that those parts could be used to as-

assembling sunglasses unless absolutely necessary. If it became
necessary to use the quarantined parts, those parts were in-
spected to sort out the unusable parts. Quarantined parts were
sometimes reworked to make them acceptable before they were used.
