Engineering enablement


Wisdom from Abi Noda

Calculating engineering metrics perfectly is impossible. Take cycle time, for example:

  • Calculating it from PR open to merge creates fuzziness based on when devs open PRs

  • If you try to calculate from "first commit", Git rebases muddy your numbers

  • Also: your metrics aren't factoring out non-working hours or weekends

  • And some teams don't use PRs at all

It's fine to settle for "good enough".

All metrics are proxies.

It's the trends and comparisons that give you the most signal.
