The Single Best Way to Be Efficient Is to Add Layers of Slack

The single best way to be efficient is to add layers of slack. If you are running an emergency room where life and death decisions happen, i sure hope you have more than a week's supply of bandages in stock. On the other hand, if you make bespoke artisonal baskets for thousands of dollars each, it's ok to run out of supplies for a week or a month at a time because no one's buying baskets from you on an emergency basis. In general, the most efficient way to keep those proms, except for the one that we're cheaper, is to build some slack into your supply cay.
