• Why is it important to consider uncertainty when evaluating supply chain design decisions?

All things being equal in a perfect world there would be no uncertainty, knowing that world does not exist we must take thing like the stock market diving and foreign currencies gaining or loosing values into consideration when evaluating supply chain design decisions. Planning for some uncertainties in a supply chain design can help to adapt and compensate when issues arise that might otherwise cause the chain to collapse.

• What are the major sources of uncertainty that can affect global supply chain design?

Economic failings both domestic and abroad can affect the global supply chain. Companies in other countries that have good and bad years or may even be failing can have a drastic impact in the supply chain. Political shifting among nations that control trade are factors to take into account when designing a global supply chain. Designing contingencies into the supply chain workings to account for these factors can help to keep the supply chain from clasping or failing all together.
