When a suite fails one in five runs for reasons unrelated to the change under test, your deployment frequency chart still looks healthy — but your change-failure rate and recovery metrics become fiction. Analysts then recommend process changes that never address the real drag.
A practical triage: quarantine known flaky cases into a separate job that does not block merge, tag failures with owner and last-green commit, and measure flake rate as its own series. Only then should failure-on-deploy feed your delivery analytics.
We often see Korean fintech and logistics teams inherit suites grown across three CI vendors. Unifying the failure taxonomy matters more than picking a new dashboard. Name the failure once — infrastructure, test instability, or genuine product defect — and keep that label through to the weekly review.
Crooked charts are not a reason to abandon measurement. They are a reason to stop treating every red build as equal evidence.
