That's a pretty broad statement with no supporting evidence. In fact, I'd argue that most large organizations rely on internal processes to be ignored or bypassed just as often as they rely on other processes to be followed.
I've been on teams that required "every feature" to go through a design review. Guess what? Suddenly a lot of what we were already working on stopped being "features" and started being "small bug fixes". Approvals for launches are often sought from the last few approvers just before launch because the list of required approvers is so long, and the VP of engineering isn't going to approve until everyone else has already approved etc... This kind of shit is par for the course at a large company because the alternative is basically a "work to rule" strike.
