I've managed warehouse operations for seven years, and I keep hearing that just-in-time logistics is the only way to stay competitive. But after the port backlogs we saw in 2021, I'm starting to think lean supply chains are too fragile for today's world. The cost savings from lower inventory can evaporate overnight when a single shipment gets delayed, and no one mentions the stress it puts on workers who have to scramble every time something goes wrong. Is the efficiency really worth the risk, or are we just one disruption away from a total halt?
