A CI system should be configured to send alerts in a multitude of ways:
- Emails
- SMS
- Push notification alerts via smartphone
Some software development offices also use some other creative ways to send issue notifications on a software build, such as some kind of ambient light change or maybe even an intercom system. The main point is that developers need to be notified that the CI build is broken so that they can quickly fix the build. The CI build should not stay broken as this can disrupt other developers work.
