For years, DORA has measured software delivery performance through two families of metrics: throughput (how often and how quickly a team ships changes) and instability (how often those changes break production and how long recovery takes). In the 2026 report, DORA links these metrics to ROI: delivery stability and speed are the basis for predicting AI returns.
Key point
Google and the DORA team published the 2026 study "The ROI of AI-assisted Software Development" (dora.dev/ai). The conclusion is uncomfortable for anyone who has handed the team AI assistants and expects speed to double: AI return on investment is determined by the system around the assistant - integrations, processes, and the maturity of the engineering platform. The assistant itself does not create that system. AI acts as an amplifier: it multiplies the return already built into the company.
