This is so key.

Software companies in general need to emphasise this so that builds are easy, CI is a given and continuous deploys are a no-brainer.

I worked with someone who went into what he called "samurai coder" mode. He'd get his digital sword out and start chopping up the enemy (bad code). We were in an environment where everything could be undone, reset, restarted, or otherwise restored, so his swordplay worked.
