Which of the following is a global supply chain challenge?

• A. Long lead times.
• B. Universal currency stability.
• C. Tariff-free trade with no barriers.
• D. Predictable demand without variability.

Answer: (A)

Global supply chains are often slowed by delays that come with international movement of goods, multiple suppliers, and cross-border processes. Long lead times emerge when components and finished products travel long distances, pass through several stages, and face potential transport hiccups, customs checks, and scheduling mismatches across time zones. These delays complicate planning, raise safety stock costs, and increase the risk that demand changes won’t be met quickly enough, which is a major challenge for meeting customers’ needs and keeping costs under control.

The other conditions would actually reduce friction in global operations: stable currencies lessen financial risk, tariff-free trade lowers barriers and speeds movement, and predictable demand minimizes variability. None of those describe a challenge in the global flow as much as extended lead times do, making long lead times the best answer.
