What is a software factory? From Ford's line to AI agents

Everyone's calling the way software gets built in 2026 a "software factory". The idea is almost sixty years old.

In this explainer, we trace the software factory from Ford's moving assembly line to the AI coding agents working on teams today, in plain language.
We get into:

What a factory actually is: standard steps, a station for each, and checks before work moves on
The 1968 NATO conference, the "software crisis", and the first use of the phrase "software factory"
How Hitachi, Toshiba, NEC and Fujitsu ran real software factories, and why most software isn't a Model T
How the line moved into machines with continuous integration, continuous delivery and DevOps
Software factories in the US Department of Defense, from Kessel Run to the 29 that government auditors counted in 2023
What changes when AI agents join the line, and what a modern software factory needs: a standard process, isolated workstations, inspection, a logbook and cost accounting
