The theory goes that if you ship code on Friday you’ll inevitably be working Saturday to fix what you broke. This makes logical sense; software is messy and mistakes are unavoidable.

But no, shipping code on Friday isn’t bad. At least, it doesn’t have to be.

The key to their success is confidence, which comes from having a solid deployment pipeline and shipping through it often. Gerhard Lazu hit that nail on the head in this short clip as well.
