+  How do you resolve issues after a deployment? Do you roll back to the previous version or fix the issue and deploy it and move forward?
+---
+
+You deploy a code change but it creates an issue.
+
+Maybe it breaks a feature, adds a bug or takes down an environment completely.
+
+How do you resolve it?
+
+Larger releases will sometimes have a roll back plan that details how to revert to the previous release.
+
+This can be difficult, especially for large releases and ones that change the database schema or values.
+
+Because of the amount of change, diagnosing an issue in a large release can take time.
+
+If it's been a while since the prior release, it can be some time since the code that introduced the issue was worked on - making it harder to fix.
+
+I prefer to do small releases and do them often.
+
+Some releases contain a single commit which was made only minutes since the previous release.
+
+This makes it easier to identify the issue, fix it and deploy a new version.
+
+No rolling back database changes or reverting to previous releases.
+
+Small, iterative deployments are less risky than large infrequent ones, easier to fix and make changes available to end users sooner.
