Parkinson's Law applies to the BBC, judging from the comments of Paxman and Dimbleby about management. Parkinson thought that managers want subordinates, not rivals and that managers make work for each other. Hence, the number of lesser managers increases with time and yet they all appear to be fully employed, so busy in fact that more managers, more subordinates, are taken on to take the apparent extra workload.
In the BBC it is evident that there must be several 'suits' who are more directly responsible, being closer to events and answerable for each decision, than Entwistle was and there are many who are entirely unnecessary.If, as seems possible but unlikely, these lesser figures are held responsible and removed over this affair and are not replaced, the saving to the public will be far greater than the expense in paying Entwistle twice the leaving salary than he was strictly entitled to; an overpayment made to encourage him to go amicably, no doubt.
