Ya, after a while in the field I noticed that Xtreme Programming, Agile, DevOps, and now Shift Left, and most other ideas are all just describing the exact same thing. Be flexible in your work, set up your processes to be able to deliver quickly so you can adjust quickly. I was puzzled why it seemed we were learning the same lessons in an industry over and over again, and why we kept giving new names to things that we're already existing. Then I received enlightenment when I realized that consultants that were selling agile previously were now selling DevOps. The reason they keep changing the name is because it allows consultants to come in and charge you more money to tell you to do the same things management bungled the last 3 times, because the problem isn't with the business processes it's with the idiots running the company. Or to quote Scott Adams "If you notice a lot of focus on process improvement at your business that's a sign all the smart people have left and management is trying to figure out a process simple enough for the idiots left."
