Zhang Ruimin

Zhang Ruimin stands as the most radical turnaround artist on this list, using a literal sledgehammer to smash 76 defective refrigerators in 1985, cementing an uncompromising quality ethos. His model of “rendanheyi” later inspired the -ranked Indra Nooyi’s own purpose-driven restructuring, yet Ruimin’s decentralized approach achieved a 30% higher employee engagement score than typical Fortune 500 appliance firms. He made Haier the world’s largest home appliance brand by market share, a concrete triumph of customer-centric management.
