Code, test, deploy often.
Get feedback fast.
Fail fast.
Die.

I’m at a slow deploy job. Like months between releases. It is awful for users. We have bugs that were architectural issues from trying to get a feature in at the last moment. So no patch for them. Architecture was fixed a week after the release. The same bug is found over and over. If we had rereleased again two weeks later it would have been so much better.
