Escalation Policy Design: Three-Tier Pattern

Escalation policies have to be predictable and unambiguous. Three tiers are the minimum that handles real situations.

Why escalation matters

Without escalation: a missed primary page becomes an outage.

With escalation: missed pages reach a human within minutes.

Three-tier pattern

Per-team timing

SEV1: T1 immediate, T2 +5min, T3 +15min.

SEV2: T1 immediate, T2 +15min, T3 +60min.

Severity decides cadence; one policy for all loses signal.

No-ack defaults

No-ack default: page automatically escalates without human action. Engineering judgement removed at 3am.

The policy must escalate without trusting the on-call to manually request it.

Antipatterns

What to do this week

Three moves. (1) Apply this practice to your next on-call rotation. (2) Survey the team after one cycle. (3) Iterate based on feedback; the discipline is the cadence.
