The thing that still confused me is how reliable supply chains are, or seem to be. The world is unpredictable—you’ve got earthquakes, labor strikes, mudslides, every conceivable tragedy—and yet as a consumer I can pretty much count on getting what I want whenever I want it. How can it be possible to predict a package’s arrival down to the hour, yet know almost nothing about the conditions of its manufacture?

In the supply-chain universe, there are large, tech-forward companies like Amazon and Apple, which write and maintain their own supply-chain software, and there's everyone else. And most everyone else uses SAP. SAP—the name stands for Systems, Applications, and Products—is a behemoth, less a single piece of software than a large, interlocking suite of applications, joined together through a shared database. Companies purchase SAP in "modules," and the supply-chain module interlocks with the rest of the suite. Among people who've used SAP, the reaction to hearing its name is often a pronounced sigh—like all large-scale enterprise software, SAP has a reputation for being frustrating.
