Catch performance regressions automatically in your pipeline, not hours later in production.

Unit tests catch logic errors; regression tests catch integration failures that unit tests miss.

Confusing functional and regression testing is why pipelines pass while production breaks.

Catch regressions introduced by new deployments before they become production incidents.

Faster deployments without verification coverage just hide problems deeper in your release chain.

Canary deployments limit blast radius but don't verify health.

Segment your MTTR by severity and deploy cadence to benchmark against what actually matters.

Detection and resolution measure different problems that need different fixes.

Undefined terms and loose calculations hide the real cost of slow incident detection.

Define your clock's start, stop, and what counts as recovered.
