Manufacturer X is building up automobile instrument panels and they continue to ignore issues caused by the operator.
Application – Install four fasteners in vent duct
Problem – If an operator missed a vent duct screw the duct would rattle when the blower was turned on
Resolution – The only way to correct the rattling noise was to take apart the dash and install the missing screw
Cost – 2 hours of labor, $0.10 screws and an annoyed customer
Solution – The customer was able to correct their missing fastener issue by implementing a line stop which is controlled by a wireless qualifier and counts each screw the operator correctly installs using a wireless tool.
