Which strategy involves maintaining multiple suppliers to mitigate risk in supply chain?

The strategy that involves maintaining multiple suppliers to mitigate risk in the supply chain is best represented by the option referred to as "Many suppliers." This approach helps organizations avoid dependency on a single supplier, which can be problematic if that supplier experiences disruptions, such as financial issues, natural disasters, or operational failures. By sourcing from multiple suppliers, companies can ensure they have alternatives available, thus enhancing their resilience and ability to maintain consistent operations.

Utilizing many suppliers also fosters competitive pricing and innovation, as different suppliers may offer varied capabilities and technologies. This strategy can lead to better negotiation power and can help stabilize supply chain processes over time by diversifying the risks associated with supplier reliability.

In contrast, single sourcing relies on just one supplier for a specific component or material, which increases vulnerability to risks associated with that supplier. Just-in-time focuses on minimizing inventory levels and can lead to challenges if suppliers are unable to deliver on time, while vertical integration involves a company taking control over more of its supply chain by owning suppliers or distributors, which is a different strategic focus that does not specifically address risk mitigation through multiple suppliers. By understanding the characteristics and advantages of using many suppliers, companies can better navigate the complexities of the supply chain.
