The reality is that well-tuned processes can reduce cognitive load in day-to-day work, freeing up mental cycles for higher level problems. But process also adds overhead and rigidity, so it needs to be tuned to the environment at hand and reevaluated regularly. This can't be done be done by a drive-by consultant or a detached manager, it requires boots on the ground context and applied expertise to relate the day-to-day reality to the highest order business goals. Anything short of that is MBAs and juniors clinging to an arbitrary process as justification for why they are delivering adequate, but not exceptional results.
