Jean Safari, an American
manager, was investigating a serious error made by a Japanese worker at the
Japanese subsidiary of a US
multinational. A component had been inserted upside down and the entire batch
had been pulled out of production to be reworked. The cost of this was high.
Jean asked the Japanese plant director about which employee had made the error.
Had she been identified? What action was being taken against her? She was
amazed when the director claimed not to know. “The whole work group has
accepted responsibility,” he told her. How do you understand this explanation?
