Global Stumble discusses the cultural differences Nomura encountered when acquiring Lehman Brothers. There were differences in decision making speed, treatment of women, and dress codes between the Japanese and American cultures. Nomura initially took an ethnocentric approach but is moving toward a geocentric attitude by promoting diversity and transferring executives overseas. Cultural research showed Japan values group success over individuals and careful decision making, while the US prioritizes speed and individual contributions. Nomura can address differences through diversity training, celebrating cultures, and seeking minority leaders.
