Harley-Davidson faced declining market share in the 1970s due to competition from Japanese motorcycle manufacturers. Under new leadership in the 1980s, Harley-Davidson implemented changes to management, marketing, and manufacturing that led to a turnaround. Management focused on continuous improvement, employee involvement, and open communication. Marketing emphasized brand image and loyalty through customer events. Manufacturing improved quality and efficiency. These changes helped Harley-Davidson regain profitability and market share.
