Severity describes how bad an incident is for the business or users; priority describes how soon it should be worked. They are related but not identical: a SEV2 with a workaround may wait behind a SEV3 that blocks a regulatory deadline. Clear severity-vs-priority language keeps triage consistent inside incident management software and prevents every alert from becoming “urgent.”
Severity vs. Priority at a Glance
- Severity answers “How bad?”: Impact on customers, revenue, data, or core journeys — often expressed as SEV1–SEV3.
- Priority answers “How soon?”: Order of work given capacity, deadlines, workarounds, and business commitments.
- They can diverge: High severity + available workaround can be lower priority than a lower-severity issue with no workaround and a hard deadline.
Practical Examples
- High severity, high priority: Checkout API down for all users — page immediately, open a war room.
- High severity, moderated priority: Regional outage with a temporary failover already active — still major, but sequence after active firefighting.
- Lower severity, high priority: Broken invoice export on the last day of the month — limited blast radius, but urgent for finance.
Best Practices
- Define Severity Levels First: Impact criteria should be written down so “SEV1” means the same thing to every team.
- Let Severity Drive Automation: Use SEV to choose channels (voice for SEV1, quieter paths for SEV3).
- Let Humans Set Priority in Triage: Priority can change as workarounds appear; severity usually changes only when impact changes.
The All Quiet Bridge
All Quiet turns severity into routing logic. Map SEV levels to different escalation policies and notification channels so critical impact wakes the right people, while lower-severity noise stays out of the night shift. Priority stays a triage decision; severity stays the automated signal.
