AI speeds up what you write, not what you can deploy
Of the two things DORA said about AI in 2024, in 2025 it observed the opposite for one — delivery throughput flipped sign — and exactly the same for the other, which is the one that costs money: more AI still comes with less delivery stability. Two consecutive reports, same sign. With the METR trial that measured a 19% slowdown where participants perceived a 20% improvement — and the caveats its own authors published afterwards, including a second trial with intervals that cross zero — what the 2026 ROI report assumes in money (one point of change failure rate, $344,000) and the four things that have to take more flow before you buy anything: an environment that looks like production, small batches, a timed rollback and telemetry by symptom.
