My credit union tells me their website will be down Saturday night for upgrades. This not only means that they don't have a good DevOps-style rapid release CI/CD system, but that they have no respect for their IT group who should not have been required to spend this week and the entire weekend planning for the upgrade. They should be spending this weekend at the movie theater watching the force awakens.
This is disrespectful of their employees and shows a lack of good management. How could management expect people to focus on a critical upgrade this week?
DevOps isn't just a software release methodology. It is a way to make your work environment predictable, stress-free, and pleasant.
