Reduce change failure rate at the source.
DORA dashboards tell you the trend. Firetiger finds the failed change, explains the evidence, and helps your team fix or roll back — improving the underlying metric instead of just reporting on it.
Why most CFR numbers are wrong
Engineering intelligence platforms compute change failure rate by matching deploys to incidents — through tickets, revert-commit patterns, or manual labels. Each method has known accuracy problems. Teams that file tickets inconsistently, that fix forward rather than revert, or that don't apply standard labels end up with a CFR number that undercounts real failures. The reported metric moves; the underlying behavior is not what the dashboard claims it is.
Firetiger measures CFR from production telemetry rather than ticket archaeology. Each verdict is a structured CFR data point sourced from what the changed services actually did after deploy. The numerator and the denominator come from the same place, so the number is honest and the trend is meaningful.
What this looks like in practice
A monitoring plan from every PR diff
Firetiger reads the diff and PR description, then generates a change-specific monitoring plan — which signals to watch, which baselines to compare against, which slices the change touches.
A verdict on every deploy
For each deploy across staging, canary, and production, Firetiger issues one of three outcomes: verified, regression detected, or inconclusive. That verdict is the CFR signal — measured from telemetry, not reconstructed from tickets.
Evidence on the PR, in Slack, on the incident
Verdicts land where engineers already work. Regression-detected verdicts include the affected scope, suspected code path, change author, and the telemetry showing the deviation.
Cleaner DORA data downstream
Export verdicts to your engineering intelligence platform (LinearB, Swarmia, Jellyfish) so the CFR number in the leadership dashboard is computed from what production actually said about each deploy.
Pairs with your existing stack
Firetiger consumes telemetry and integrates with the tools your team already runs. The observability platform stays; the incident tool stays; the DORA dashboard stays. Firetiger fills the verification gap between them.
