Re: I'm not a developer but this is a genuine question...
You're missing the point. The whole point of DevOps is to shift blame and workload entirely onto the developers.
No specification? Tough, just keep guessing and shoving out updates until your guess equates to the requirement.
No oversight? Well that's your fault, that suddenly was the developers' baby as well.
Blame? Oh that goes squarely into the developers' lap, because if the solids hit the ventilation, management didn't know what the naughty developers were up to.
DevOps is an utter abrogation of management responsibility, and is deliberately engineered so that the developer gets the blame if it goes wrong whilst the management gets the credit if it goes right.
It is a fraud built on a Ponzi scheme anchored in a software South Sea Bubble.
