To me, we are looking for the Goldilocks solution: enough stock, enough time, enough speed.
Just in time works best where supply chains are VERY close to each other. Otherwise, you do need SOME items just in case manure hits the supply chain.
Has there been any stdies done in the REAL WORLD where just in tine actually works, and actually saves time and money.
Some items do need speed. But there is a price to be paid. Literally.
