I see this at work EVERY day and have been railing about it.
How Just-In-Time Manufacturing/delivery caused global shortages in EVERYTHING, with only a little nudge from COVID-19
I'd been telling anyone who would listen, for years, that we needed to keep at least a couple months' worth of inventory in stock in order to facilitate even normal operations. But every time I brought it up, our executives hissed like vampires exposed to sunlight, and swore up and down that being 100% inventoryless was the only way to stay efficient and competitive, because "it costs too much to warehouse product."
Well, now we're having to push back projects because our policy of "just in time" ordering of product to use to fulfill our contracts... isn't even remotely "just in time" any more.
