"Please don't talk about risk with so much at stake. Just push that code you wrote this morning to our mission-critical production system."

"We can do proper code review, unit testing, integration testing and full test cycle later on, when the pressure fades away."

We engineers all understand the risk of pushing untested code to production, but when it comes to medicine and other fields, we forget everything and rush it out. We basically act based on fear and hope.
