The downside is that lean inventories leave companies vulnerable to any disruption of [[supply]], for instance in the [[food distribution system]] or [[food production system]]. If [[transportation]] ([[UPS]], [[post office]], [[Fedex]], [[truck]]s, [[ship]]s, [[railroad]], and [[airplane]]s) gets snarled due to a [[Labor strike#Trucker Strike|trucker strike]] or bad [[weather]] or a [[disaster]], or if [[communication]]s get disrupted, or a parts vendor has a [[strike]] or a [[production]] problem, then [[assembly line]]s grind to a halt. Just one missing part means that no finished products go out the door.

The kanban concept has also been taken up by most of [[America]]'s [[retail]]ers (with Wal-Mart leading the way), most notably its grocery sellers. In the old days — say, twenty years ago — [[grocery store]]s had well-[[stock]]ed back rooms, with many extra cases of dry [[goods]]. But now in most [[store]]s the back room has been replaced with just a pallet-breakdown area. Merchandise comes in from distribution centers and it all goes immediately to the [[consumer]] shelves out front. Thus, what you see on the grocery store shelf is all that the store has on hand. What you see is what you get. The [[barcode]] [[scanner]]s at the checkout counters feed a complex reordering system. If Mrs. Jones buys three jars of [[pasta]] sauce, that could [[trigger]] a reorder for three more jars. As long as [[communication]]s and [[transportation]] work smoothly, then the entire system hums along like a [[Swiss]] watch. But what happens when the transportation [[infrastructure]] gets disrupted? [[Panic]] buying can clean out supermarket shelves in a matter of hours. The important lesson in all this is to get [[prepared]] in advance. Do not count on being able to buy anything to provide for your [[family]] on or after a [[disaster]], or worse such as [[SHTF]] or [[TEOTWAWKI]].
