准时制生产：高效却脆弱

Many factories now build cars or phones only when orders arrive, not before.
This method cuts storage costs and avoids leftover stock piling up in warehouses.
But if a key part fails to ship on time—say, a chip from overseas—the whole line stops.
The 2021 global chip shortage showed how one small delay can freeze production worldwide.
Firms using this system often keep no backup suppliers, trusting perfect timing instead.
When storms hit ports or borders close suddenly, deliveries stall within days.
Consumers notice empty shelves long before managers realize the chain has broken.
Still, companies love it because it boosts short-term profits and reduces waste.
Yet resilience now means holding *some* extra parts—not just chasing speed and savings.
Thinking about supply chains helps us understand why small disruptions ripple so far.
