Is Just in Time a Time Bomb?

Just in time manufacturing is problematic for a lot of reasons. A single interruption causes cascade effects. Grocery stores don't have any extra soda in the back. They get behind. Demand builds up distribution doesn't have any palots in the warehouse. So they can't answer the surgeon demand from grocery stores. Manufacturing doesn't have spare parts for aging equipment, so we can't boost production. Spare parts makers don't have stock built up. The actual proximate cause of this is de regulation of capitalism that has incentivized quarterly profits and made long term thinking anathema to ceo. But sure, conservatives blame california for not letting old trucks off load at the ports.
