What are the different phases in DevOps?

Perhaps solid, liquid, gas, plasma, Bose-Einstein condensate? In all seriousness, DevOps is marketing BS - the phases are different based upon the vendor you speak with, lol.

For example, one vendor has the 5 phases of DevOps maturity, which are the following:
- Level One: Ad Hoc (Chaos Reigns)
- Level Two: Repeatable (Continuous Integration)
- Level Three: Defined (Continuous Delivery)
- Level Four: Measured (Continuous Deployment)
- Level Five: Optimized (Continuous Operations)

The truth for any organization can be anywhere on this type of chart, depending on the teams, the department, how the wind is blowing, etc. If you want to get a good laugh, just google image search the memes for devops, agility, CI CD, etc. Enjoy!
