No one should care about devops’s consent when they’re given a work item that comes from someone higher up on the org chart. Their consent is willful employment. Similarly, no one should care about an engineer’s consent when given a work item in a similar context.

If the engineer proposes an implementation the devops team doesn’t like, the devops team should come up with a counter proposal that still fulfills their requirements. And if their counter proposal fulfills the requirements but the engineer objects, then whoever’s at the top of both their branches in the org chart should be making the decision.
