Roles per state

• New — QA report.
• Assigned — Lead triage.
• In Progress — Dev fix.
• Fixed — Dev mark, push to QA env.
• Verified — QA confirm fix.
• Closed — Lead close.
• Reopened — fix fail verify → back to In Progress.

Triage process

• Daily / 2x weekly bug triage meeting.
• 15-30 phút.
• QA Lead + PM + Dev Lead.
• Decide: severity, priority, owner, target release.

Severity vs Priority

• Severity — technical impact (crash > broken feature > UI glitch).
• Priority — business urgency (revenue blocker > customer ask > nice-to-have).
• Có thể: Critical severity + Low priority (crash khi 1 user dùng dark mode + small screen + offline + edge case → fix sau).

Aging report

• Bugs open > 30 days: review weekly.
• Bugs open > 90 days: escalate.
• Bugs > 180 days: closed-deferred or back to backlog.

SLA per severity

• Critical: 4h response, 24h fix.
• High: 24h response, 1 week fix.
• Medium: 3 days response, 1 month.
• Low: backlog.
