American Computer Giant IBM decided to have some parts manufactured in Japan as a trial.
In the specifications, they set standard that they will accept only three defective pieces per 10,000 pieces.
When the delivery came to IBM there was a letter accompanying it.
"We, Japanese people, had a hard time understanding North American business practices.
But the three defective parts per 10,000 pieces have been separately manufactured and have been included in the consignment in a separate package mentioned
'Defective pieces as required; not for use.'
Hope this meets your requirement.
In some workplaces Perfection is a Habit, not an Attitude.
