the wall of confusion
expressionops culture
The dysfunction where developers and operations hand work back and forth without shared ownership.
Dev throws code 'over the wall' to ops and walks away; ops catches the fallout and blames dev - each side optimizing locally while the whole suffers. Naming the wall of confusion was part of what launched DevOps, whose whole point is to tear it down with shared goals and tooling.
Also known as: throw it over the wall, dev vs ops wall
