What defines a supply chain disruption?

A supply chain disruption is characterized by any event that interrupts or disturbs the normal flow of goods within the supply chain. This could involve delays, sudden shortages, or any unexpected situations that hinder the movement of products from suppliers to consumers. For instance, natural disasters, political instability, or manufacturing issues can lead to such disruptions, significantly affecting how businesses operate and fulfill customer demands.

In contrast, the other options do not encapsulate the nature of what constitutes a disruption. A planned interruption in the supply chain refers to activities arranged in advance for maintenance or upgrades, and does not represent an unforeseen event. A routine maintenance procedure is a regular activity aimed at ensuring operational efficiency and does not imply any disruption to operations. Lastly, an increase in supply chain efficiency signifies improvements and enhancements rather than interruptions or disturbances. Therefore, option B stands out as the most accurate definition of a supply chain disruption.
