Readiness
The state of being fully prepared for an action or activity. Service Readiness ensures that the support teams, documentation, and users are ready for a new release.
Impact
Code readiness != Release readiness. The code might work, but if the support team doesn't know how to fix it, you aren't ready.
Weinto take
We use Operational Readiness Checklists (ORC) as a gate in the pipeline. Can we monitor it? Is there a runbook? Is there a backup policy? If the answer is no, the pipeline blocks the deployment. Readiness is enforced by the machine.
