Amazon Web Services (AWS) created the Operational Readiness Review (ORR) to distill the learnings from AWS operational incidents into curated questions with best practice guidance. This document is intended to help you understand how the AWS ORR program was built and guide you in creating your own ORR program as part of the AWS Well-Architected Framework. Creating an ORR program can help supplement Well-Architected reviews by including lessons learned that are specific to your business, culture, tools, and governance rules.
