- The DX Core 4 is a unified framework for measuring developer productivity, combining DORA, SPACE, and DevEx into four dimensions: speed, effectiveness, quality, and business impact.
- It has been successfully implemented at over 300 organizations, yielding a 3-12% increase in engineering efficiency, 14% more R&D time on feature development, and a 15% improvement in employee engagement.
- The framework is multi-dimensional, supports all organizational levels, can be deployed in weeks, and avoids fear and gamification by balancing speed metrics with experience data.
- The metric 'diffs per engineer' requires careful use with counterbalancing, no targets/rewards, and proper communication to prevent abuse.
- Data is collected via system metrics, self-reported data, and experience sampling to provide a comprehensive view of productivity.
- To get started, organizations should establish baselines with self-reported data, start small, and communicate transparently with teams.
