Operational Readiness Reviews (ORRs) - Reliability Pillar

Operational Readiness Reviews (ORRs)

AWS finds it useful to perform operational readiness reviews that evaluate the completeness of the testing, ability to monitor, and importantly, the ability to audit the application's performance to its SLAs and provide data in the event of an interruption or other operational anomaly. A formal ORR is conducted prior to initial production deployment. AWS will repeat ORRs periodically (once per year, or before critical performance periods) to ensure that there has not been “drift” from operational expectations. For more information on operational readiness, see the Operational Excellence pillar of the AWS Well-Architected Framework.

Recommendation
Conduct an Operational Readiness Review (ORR) for applications prior to initial production use, and periodically thereafter.
