Observability & Operations

Operational model​

For each critical pipeline and model define:

  • owner
  • schedule
  • freshness target
  • success criteria
  • alert
  • runbook
  • recovery procedure
  • escalation

SRE metrics​

Use:

  • availability
  • freshness
  • completeness
  • failure rate
  • MTTD
  • MTTR
  • reconciliation pass rate
  • change failure rate

Control tower​

Build an operational view covering:

Ingestion → Transformation → Modeling → Consumption → Business KPI

A green pipeline is not sufficient if the business KPI is wrong.

Incident workflow​

Detect → Triage → Contain → Diagnose → Recover → Reconcile → Communicate → Prevent

Every major incident should produce a root-cause record and a prevention action.
