On-call

Make on-call predictable, coachable, and sustainable.

On-call readiness is the ability to diagnose, mitigate, and communicate under pressure using the tools and constraints you actually have. The goal is consistent performance across the team, not heroics.

The Reality

Scaling breaks tribal knowledge.

Readiness rarely improves from postmortems alone, especially while hiring fast.

Ramp is chaotic

New engineers join the rotation before they’ve built operational intuition on your systems.

Runbooks drift

Docs exist, but they’re outdated, incomplete, or don’t match how systems fail in practice.

Outcomes hide causes

MTTR is an outcome; it doesn’t tell you what capability is missing, or what to coach next.

Framework

A practical readiness framework.

Four dimensions you can train and measure over time.

Detection + triage

Identify which alerts matter and find the fastest path to “what changed” and “what is broken”.

Diagnosis under ambiguity

Narrow hypotheses using metrics/logs/traces without getting stuck in noise or false leads.

Safe mitigation

Use low-risk mitigation paths (flags, rollback, degrade) with verification and blast radius awareness.

Communication + follow-through

Keep a clear comms cadence and ensure the fixes land: runbooks, alerts, telemetry, and guardrails.
