DevOps uses a capability model, not a maturity model
DevOps as a movement died when it started being used as a job title. In my experience, it quickly stopped being a philosophy for Dev and Ops teams to work on working better together and just because a new name for System Administrator.Before the popularity of the term "DevOps" it was always true that any System Administrator worth hiring knew how to script for automation (the job title for people who didn't was System Operator). Unfortunately the market was flooded with a lot of people in that role who barely knew what they were doing and so resisted every change anyone else in their company wanted.From my perspective, the greatest achievement of the DevOps movement was to push the bar higher for the expected skill level of the average SysAdmin. I see that as a good thing.
