How to Measure AI Developer Productivity in 2025 | Nicole Forsgren

Summary

Nicole Forsgren, creator of the DORA and SPACE productivity frameworks and Senior Director of Developer Intelligence at Google, argues in advance of her new book Frictionless that traditional developer productivity metrics are often misleading and must be replaced with measures centered on developer experience. She outlines a practical framework for DevEx teams focused on three components—flow state, cognitive load, and feedback loops—and notes that while AI tools like Copilot and Gemini speed coding, they haven’t delivered proportional developer speedups. The guidance signals that companies should retool measurement and org design to capture real AI-driven gains and reduce friction if they want to convert tooling advances into measurable business velocity and lower delivery costs.
