I have worked in three organizations that used SAP. All three had problems and the high sunk costs made it hard to move elsewhere. I think a good way to measure theefficiency of the systems is to call three random admins or secretaries at an institution. In my experience, everyone complained about version incompatibilities, speed, logic (I got to see the UX once, it was a nightmare).
I would estimate using the SAP systems costs about 10% of productivity (net after gains through digitalization of processes).
