In which instance would multiple sourcing be the most applicable approach?

Multiple sourcing reduces dependency risks and provides flexibility in urgent supply situations. For components needed at short notice, having multiple suppliers ensures continuity and responsiveness. Strategic, high-value, or unique components (B, C) often require single or closer sourcing to ensure collaboration and expertise. Service provision (A) typically benefits from relationship-based sourcing rather than multiple arrangements. Responsible sourcing stresses that multiple sourcing is a risk management tool, best applied where speed, availability, and resilience are essential.
