Diversification and Regionalization
The pandemic exposed the risks of overreliance on single suppliers or regions, particularly China, which accounts for 20 percent of global manufacturing output. To build resilience, companies are diversifying sourcing and embracing regionalization.
Nearshoring and Reshoring
Nearshoring (relocating production closer to end markets) and reshoring (bringing manufacturing back to home countries) have gained momentum. These strategies reduce dependence on distant suppliers and shorten lead times. For instance, in 2023, Apple expanded manufacturing in India and Vietnam to diversify its supply chain away from China. Similarly, the U.S. government invested $52 billion through the CHIPS Act to boost domestic semiconductor production, reducing reliance on Asian suppliers.
Regionalization also mitigates risks from global disruptions, such as shipping delays or trade disputes. A 2024 survey by PwC found that 65 percent of North American companies planned to increase nearshoring efforts over the next five years, citing faster response times and lower geopolitical risks.
Multi-Sourcing Strategies
Multi-sourcing, or procuring materials from multiple suppliers across different regions, has become a cornerstone of resilient supply chains. This approach minimizes the impact of disruptions in one region. For example, during the pandemic, automakers like Toyota shifted to multi-sourcing for critical components like microchips, enabling faster recovery from shortages. According to a 2024 report by Bain & Company, 70 percent of global manufacturers now prioritize multi-sourcing to enhance supply chain stability.
Automation and Workforce Resilience
Labor shortages during the pandemic, caused by lockdowns and health concerns, underscored the need for automation. Robotics and autonomous systems have emerged as key solutions for maintaining operations in challenging conditions.
Warehouse Automation
Automated warehouses, equipped with robotic picking systems and conveyor belts, have reduced reliance on manual labor.
