DX Core 4 Framework Metrics
- The DX Core 4 metrics framework measures developer productivity using Speed, Effectiveness, Quality, and Impact.
- Speed is quantified by pull requests merged per engineer at team or organizational level, not individually.
Avoid Gamifying Developer Metrics
- Avoid measuring speed metrics at individual developer level to prevent gaming by splitting work into many small pull requests.
- Combine multiple metrics like speed and quality to get a balanced view of productivity.
Effectiveness Drives Developer Hours Saved
- The Effectiveness metric is qualitative, derived from developer survey questions about documentation, focus time, and change confidence.
- Improving developer experience index by one point saves 10 hours per developer per year, which translates into significant cost savings.
