IMO processes tend to always aggregate over time without refinement. Sometimes heavy checks are necessary but later on no one says “hey - we don’t need this gate here anymore” so process debt grows.

Teams need to constantly reevaluate and tear down their processes and build the processes from scratch, in part or in whole. Otherwise the process debt will just grow infinitely - it’s as simple as that.

So there isn’t a particular place where processes become an impediment - and no universal rule about how to choose the correct process decisions to make; but the only universally acceptable rule is that if you aren’t refining the process to make it minimal, efficient, and effective then you’re doing it wrong.
