Repeatable processes for bug triage, regression testing, handoffs.
Twelve concrete rules for filing, triaging, and closing bugs: one bug per ticket, always attach a reproduction, split severity from priority, verify before you close.
MTTR is a core DORA metric, but the segment that dominates is usually diagnosis, not the fix. How to measure it honestly and cut the biggest lever.
The QA metrics that actually predict release quality (defect escape rate, defect density, MTTR, reopen rate), with formulas, benchmarks, and vanity metrics to drop.
Define incident severity levels SEV1 to SEV5 with a copy-paste matrix: examples per level, response SLAs, who gets paged, and how SEV differs from bug priority.
Reduce the QA-to-dev bug bounce rate. Why tickets bounce as cannot reproduce, the six-field handoff that stops it, and how an attached replay collapses the round-trip.
A repeatable weekly bug review meeting: copy-paste 45-minute agenda, attendee roster, fix/wontfix/defer/dupe decision rules, and metrics to shrink your backlog.
Copy-paste blameless postmortem template plus a worked example, root-cause categories, and SRE-grade triggers, based on Google SRE and PagerDuty.
A bug status workflow (New through Closed, plus Reopened and Will Not Fix) that scales from 3 to 300 engineers, with per-severity SLAs and clear transition owners.
A step-by-step bug bash playbook: prep, timeboxed run, and same-day triage, with roles, a copy-ready report schema, and a scorecard with formulas.
A measurable playbook to drive down cannot-reproduce bug tickets: capture the session replay, log environment and viewport, standardize the report, and track the rate.
A risk-based regression testing playbook: what to re-test after every release, smoke vs full, and when to automate versus probe by hand.
A go/no-go release readiness checklist plus a blocker-versus-non-blocker framework and DORA change-failure-rate framing for safer shipping.
Separate bug severity (technical impact) from priority (business urgency) with a decision matrix, the four quadrants, ownership rules, SLAs, and honest caveats.
A repeatable 5-step playbook to triage production bugs in 15 minutes, from page to severity assignment to first action, without losing your sprint to investigation.
