I like this response on measuring engineering:
In my experience, the “right” answer, i.e. the best way to run consistently high-performing teams, involves some combination of the following:
- Outcome-based management that practices focusing on impact, plus
- Team level health metrics, combined with
- Engineering ladder and regular lightweight reviews, and
- Managers who are well calibrated across the org, and encouraged to interrogate their own biases openly & with curiosity.
