- Distributors have changed delivery schedules to work around New Year's Eve and Day.
- There's a large increase in demand for produce and some other ingredients (resolutions)
- Employees at the store and regional level take a few more vacations than usual, since we aren't able to during much of the holiday season. People also tend to plan the hell out of ordering for Thanksgiving and Christmas, but relax too much by New Year's since they figure crunch time is over. This is made worse by the relatively short tenures of most store buyers, since they either move up or quit relatively quickly.
So I would say there probably was a nationwide spike in out-of-stocks spread out over a few days. But it isn't really because of OTS.
Is it though? If OTS drastically decreases the backstock, wouldn't it also decrease the ability of a store to respond to these kinds of changes?
Also, OTS allows backstock of top selling items or in emergencies. If you can predict a big storm like what probably caused most of the problems in the article, you are allowed to stock up on product.
That's why I have a problem with the article, it's just so factually incorrect.
