Measure time to first response, time to first review, and newcomer pull‑request merge rate before counting stars. These signals forecast health earlier and are easier to influence through habits. Share results transparently, invite discussion, and co‑create experiments that move trends together without sacrificing kindness, rigor, or long‑term maintainability.

Group contributors by start month and follow their participation over time to spot onboarding gaps and mentorship wins. When cohorts persist, celebrate the practices that helped. When they fade, redesign rituals and documentation. Treat the data as a story starter, then act compassionately and iterate quickly with the community.

Track comments thanking reviewers, notes about feeling welcome, and posts describing developer experience. These artifacts illuminate texture behind the numbers and reveal where caretaking pays dividends. Share excerpts in meetings to humanize trade‑offs, and let stories inform priorities alongside graphs, encouraging empathy while you scale responsibly together.
