What is a key factor that contributes to the fragility of supply chains for the DoD?

A key factor that contributes to the fragility of supply chains for the Department of Defense (DoD) is the presence of limited domestic suppliers. When the number of domestic suppliers is restricted, the supply chain becomes more vulnerable to disruptions. This limited supplier base can lead to increased risk since fewer sources mean that the DoD is more dependent on each supplier's capability to meet demand. Should a supplier face difficulties, whether due to financial troubles, natural disasters, or other unforeseen issues, the entire supply chain can be significantly impacted. This dependence also limits the flexibility needed to adapt to changing requirements or supply challenges.

In contrast, having multiple domestic sources or increased global competition typically enhances resilience, as it diversifies risk and provides alternatives when challenges arise. Technological innovations can improve efficiency and processes within supply chains but do not directly address the fragility caused by supplier limitations. Thus, while all these factors are relevant to supply chain dynamics, the limited number of domestic suppliers stands out as a critical factor contributing to the fragility faced by the DoD.
