Delivery metrics
Mean time to recovery
Mean time to recovery (MTTR) is the average time it takes to restore a service after a production failure, from the moment an incident starts to the moment normal operation resumes. One of the four DORA metrics, it captures how quickly a team can detect, respond to, and recover from a bad change.
CI/CD practice
Merge queue
A merge queue is a CI/CD mechanism that lines up pending pull requests, rebases each on top of the current tip of the target branch, re-runs the required checks, and only merges when they pass. It prevents "semantic conflicts" - where two individually green pull requests break the trunk once combined - by making every merge sequential and re-verified.
