One approach to managing supply risk is having multiple suppliers for a product.

Multiple sourcing is most suitable for strategically important, high-value requirements such as raw materials. This approach reduces dependency on a single supplier, improves resilience, and increases competition. One-off requirements like machinery (A) are not suited to multiple sourcing, while options B and D describe disadvantages, not benefits. Responsible sourcing requires risk mitigation strategies tailored to the category, and multiple sourcing is effective where continuity and bargaining power are critical.
