What has happened is not “mismanagement”. That at least suggests a semblance of organisational structure or operational systems which have then somehow been misused. Procedural mishaps. That sort of thing.
No, what has gone down at Eskom and other SOEs is that they have been utterly destroyed, eviscerated by ravening criminals. There is frankly very little here to “overhaul”. All have been reduced to wreckage in the nihilistic free-for-alls that have left once-powerful entities like the railways, SAA and the national broadcaster little more than broken shells.
