I just read The Phoenix Project, the book mentioned at the end of the article. It's an entertaining look at what DevOps is supposed to be like, based on things happening at various real enterprises.

The main character takes over an IT organization that's way behind on deadlines and experiencing one major disaster after another. He gradually transforms it with better practices, until everybody's living a stress-free, balanced life, and they're delivering much better results to the business.

These two things don't need to be in conflict.
