The Observability Maturity Model in Five Stages

Honest about where teams are and what the next step is. Most teams sit between stages 2 and 3 and overestimate their position.

Stage 1: logs and ssh

Engineers ssh into boxes; tail logs; sometimes write a dashboard nobody else can read. The system survives because someone always knows.

Cost: low until incident; then very high. Recovery depends on tribal knowledge.

Stage 2: dashboards and alerts

Stage 3: SLOs and tracing

SLOs defined per service; tracing instrumentation across the request path; postmortems with action items.

Cost: meaningful engineering investment in observability as a discipline. Recovery time and burnout both improve.

Stage 4: unified telemetry

All telemetry flows through one pipeline (OpenTelemetry); queries cross metrics, logs, traces; dashboards composed from one data source.

Cost: migration from prior tools. Payback is faster diagnosis and lower aggregate spend.

Stage 5: agentic remediation

The test that places you

Three moves. (1) Self-assess honestly: which stage describes your team in week 3 of an incident-heavy quarter? (2) Identify the next-stage capability you do not have. (3) Plan a quarter to add it; do not skip.
