Evolution of Supply Chain Management and Recent Disruptions
This timeline highlights key developments in supply chain management, from early concepts to modern challenges and India's policy responses.
Supply chain management evolved from internal operational efficiency to complex global networks. The emphasis shifted from pure cost-efficiency (JIT) to resilience after major disruptions like the 2008 crisis and, more significantly, the COVID-19 pandemic. This has led to a strategic rethink, including diversification and regionalization.
