+  Your CI pipeline should be what determines if a commit is deployable or not.
+---
+
+How do you know if a commit to your codebase is deployable?
+
+What gives you confidence if a change will work once it's released?
+
+This can be from manual testing but also automated testing and quality checks from tools such as static analysis and code linting.
+
+However, this relies on every Developer running them before pushing each change and for their development environments to be consistent and matching the target environment.
+
+This can be automated by using a CI pipeline - a series of checks that are run automatically for each code push.
+
+This can include running automated tests, linting code and running static analysis and anything else you need.
+
+This is what determines if the change is deployable.
+
+If your CI pipeline passes, the commit is good can be deployed.
+
+If it fails, the commit should not be deployed and you should get it passing again as quickly as possible as [there's no value in a broken CI pipeline][0].
