What are the five stages of an observability maturity model?

Initial → Monitoring → Observability → Proactive → Optimized: reactive firefighting, then defined metrics, then root-cause analysis across the three pillars, then early detection of anomalies, then data-driven automation.

Staircase of the five maturity stages from Initial to Optimize, each labelled Reactive, Visible, Understandable, Predictive, Autonomous

* Five stages, each with a capability word: what you can know about your system changes at every step. *

Stage Name Focus
1 Initial Reactive troubleshooting
2 Monitoring Watching defined metrics
3 Observability Root-cause analysis across logs, metrics and traces
4 Proactive Detecting anomalies and risks early
5 Optimize Data-driven optimisation and automation

The same progression stated as capabilities: Reactive → Visible → Understandable → Predictive → Autonomous. That phrasing is the more useful one, because each word names what changed about the knowledge available, not about the tooling:

  • Reactive: you learn about problems from users.
  • Visible: you can see the state of your systems.
  • Understandable: you can explain the state you see.
  • Predictive: you can anticipate states you have not reached yet.
  • Autonomous: the system responds to them without you.

Stages cannot be skipped in practice: tracing without reliable metrics leaves you with no baseline to compare against, and automated remediation built on data you do not trust simply automates your mistakes.
