What’s the bare minimum you should be doing? Tick all these boxes and you are on you way to being an effective team. If you’re missing any - you probably aren’t.

Continuous Integration (CI)

• Changes are merged back to the main branch as often as possible
• Changes are validated by doing a build and running tests

Continuous Deployment (CD)

• Code is deployed to automatically
• You have an automated release process
• You can deploy at any time

Unit Tests

• You have metrics that measure your code coverage/unit test quality
• They are run against the code automatically
• You can’t merge unless the tests pass

Code Reviews

• You have a working code review process
• You can’t merge without code being reviewed (properly reviewed!)

Running locally

• You can debug and test either the whole or parts of the system locally
• “Our system is too complicated to run on a developer’s machine” - is not an acceptable statement

There’s plenty of other stuff you can and should be doing, but for me the above is the bare minimum you can get away with.
