What happens when CI actually works
These teams eliminated flaky test noise, cut merge times by 75%, and reclaimed thousands of engineering hours - without building it themselves.
P90 time to merge down 30%. 50% of merge queue failures eliminated.
330 hours saved in 35 days -9.4 hours of engineering productivity back per day.
Flaky tests surfaced, quarantined, or fixed -not ignored.
CI reliability from 70% to 90%+. 10,000+ PR runs unblocked.
75% merge time reduction on day one -from 6+ hours to 90 minutes.
160 PRs/week, 20-minute average queue time.
30-40 PRs merged per day. Engineers submit and walk away.
“"We would have never known how many flaky tests we had exactly, or to what level each of them was flaky. Now we say it meets this level, and that's it - it's quarantined."”
