With supply chain disruptions occurring more often and on a larger scale, it’s natural for business leaders to want to address every weakness to avoid future issues. Yet the notion of creating a completely disruption-proof supply chain is now largely considered unrealistic. Instead, a more practical and adaptable approach has emerged—one that automakers are increasingly adopting. As industries strive to enhance supply chain resilience, the automotive sector’s strategic responses to recent challenges provide valuable lessons for businesses across the board.

A more effective method is to achieve a balance between centralized and decentralized decision-making. One automotive company used a hybrid model, putting tactical or more straightforward decisions in the hands of employees working on the ground in day-to-day supply chain operations while the central supply-chain-resilience team controls larger decisions that may involve significant investments or affect the entire supply chain. For example, the procurement team has the authority to make targeted adjustments to inventory policies, whereas the central team makes strategic decisions, such as prioritizing the list of priority risks and solutions throughout the company's supply chain. The company thinks this structure will allow it to respond more quickly to urgent situations while guaranteeing thorough diligence for changes with wider repercussions. Providing a "good enough" product:  Some automakers avoid shipment delays by modifying or deleting non-essential features and components. Their reasoning is that, following the supply challenges of the last few years, people are more willing to tolerate a product that does not provide everything they desire. Automakers have discontinued driver assistance systems and other technologies that rely on obsolete computer processors. As the chip shortage eases, it's unclear when automakers will reverse their judgments. For example, if an analog control panel is less expensive than a digital one and clients prefer analog, is it worth switching back? Weighing customer preferences, the competitive landscape, and supplier availability can help organizations make short and long-term decisions. ...Read more
