Service Owner Guide

Service owners use the blue book to launch, operate, migrate, and support production services safely.

Read first

Start with:

Service owner responsibilities

Service owners should know:

  • What the service does and who uses it.
  • How it is built, deployed, rolled back, and observed.
  • What dependencies it has and how they fail.
  • What data it handles and how it is protected.
  • Who responds to incidents and escalations.
  • What costs it creates and how ownership is tagged.

Launch checklist

Before launch, confirm:

  • Repository, pipeline, artifact, and runtime links exist.
  • Dashboards and alerts route to the right team.
  • Rollback or disablement path is documented.
  • Secrets and access are least privilege.
  • Runbook covers common failure modes.
  • Service catalog entry is complete.

Watchouts

  • Owning code is not the same as owning production behavior.
  • Alerts without runbooks create responder pain.
  • Dependencies need failure behavior, not just a list.
  • Production readiness decays unless reviewed after major changes.
