How to measure AI developer productivity in 2025 | Nicole Forsgren

Nicole Forsgren created the most widely used frameworks for measuring developer productivity—DORA and SPACE. She wrote the foundational book Accelerate and is about to release her newest book, Frictionless, a practical guide for helping teams move faster in the AI era. She’s currently Senior Director of Developer Intelligence at Google.

We discuss:

1. Why most productivity metrics are a lie [12:02]

2. Signs that your engineering team could be moving much faster [26:49]

3. Why AI accelerates coding but developers aren’t speeding up as much as you think [33:32]

4. AI’s impact on engineers getting into “flow” [08:33]

5. Her framework for building and scaling a developer experience team [36:35]

6. The three components of developer experience: flow state, cognitive load, and feedback loops [09:06]
