In the 1970s, both Walmart and Kmart adopted barcodes. Both
saw faster checkout, fewer errors, lower labour costs. The
first-order win was identical for both.
Walmart treated the barcode as a coordination layer.
Every scan fed a satellite network that connected stores,
warehouses, and suppliers into one system. Walmart could
renegotiate supplier terms in real time, restock proactively,
standardise SKUs across thousands of stores. Kmart treated
the barcode as a checkout speedup. Same technology. Different
architecture.
A decade later, Walmart had restructured the entire retail
industry - and Kmart was on its way to irrelevance. The
technology didn't make the difference. The choice of frame
did.
