Outer Dev Loop

The outer dev loop is everything else that happens leading up to release. This includes code merge, automated code review, test execution, deployment, controlled (canary) release , and observation of results. The modern outer dev loop might include, for example, an automated CI/CD pipeline as part of a GitOps workflow and a progressive delivery strategy relying on automated canaries, i.e. to make the outer loop as fast, efficient and automated as possible.
