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.
