My favourite computerised stock control story was General Electric and their mad adherence to a mad six-sigma quality standard.
"Six Sigma is a disciplined, data-driven approach and methodology for eliminating defects (driving toward six standard deviations between the mean and the nearest specification limit) in any process ? from manufacturing to transactional and from product to service."
Story I heard somewhere was that they were shipping thousands of light bulbs between far locations in Europe.
Their computer program ran. Lorries were loaded, drivers were hired, and the delivery got under way for, say, 40000 florescent lamp tubes.
For some reason, only 39999 tubes actually got sent. One was missing.
No problem, computer program ran again. One lorry was loaded, a driver was hired, and the delivery sent, this time as urgent to fulfil six-sigma.
Yup, one 40ft truck and a single fluorescent tube thrown in the back.

It arrived broken :-|
