One of the implementation on code is the Pull Request model (PR) popularized by GitHub. The main reasoning behind is that only a small set of maintainers of the product will be allowed to merge code into the release branch. Every new feature/bugfix will happen on a new branch and once done will be defined as a pull request. This allows to test on the ...

Assumptions I am making the assumption here that Jenkins, TeamCity or similar is being used as the CI/CD tool of choice. Additionally GitHub is being used and that there ...

In the case of off-hours emergency fixes, it's more practical to require less sign-off for changes than your normal procedure. Generally, you can deploy a fix and then do post-approvals the next business day. If the fix is not approved, it can be reverted and replaced with a permanent solution. During an outage situation, the number one priority should be ...
