# Chief of Staff at Series D and Beyond
The role stops advising and starts acting. Years of accumulated organisational knowledge make it possible to decide in place of the chief executive, and that is either the most useful version of the job or the most dangerous one. The difference is entirely whether the authority is written down.
Unwritten proxy authority fails the same way every time. It works for a year, because the person exercising it is careful and well informed. Then a decision goes badly, or a functional leader who was overruled decides to test it, and there is no document saying what was delegated, by whom, within what limits. At that point the organisation concludes it has been operating a shadow executive team, and it is not entirely wrong. The role does not recover from this, and the chief executive's judgement is questioned alongside it.
The second failure is quieter.
