I don't see what's different between public administrations and large corporations here. You say that the efficiency metric is non-existent in public administration, but it's mostly the same for many organizations within large corporations as well. Efficiency metrics may not be entirely non-existent, but they're incredibly opaque or difficult to measure. (For instance, R&D efficiency is usually difficult to measure because of the inevitable time delay between successful R&D efforts and market success.)
