Why efficiency can become a maintenance bottleneck

Using Britain's 2021 heavy-goods-vehicle driver shortage as an analogy, the video distinguishes delayed transport from the deeper failure caused by a shortage of mechanics. When vehicles cannot be maintained or repaired, fewer supplies move, creating a second-order shortage that further weakens the logistics network. Just-in-time systems minimize inventory and capital tied up in warehouses, making them attractive from a financial perspective. Their lack of spare capacity becomes a liability when equipment breaks down even in peacetime, and wartime adds deliberate damage to the same system. Repair ships represent the redundancy that a campaign needs even when it looks inefficient on a commercial balance sheet.
