I am not sure that bringing in a swiss team will improve the quality of the management.
Had there been any foresight, WB and his lot should have been looking into developpping there people from the onset. Well we know what happened there and the result not only of this oversight but of many others some ill intended.
One of the problem that now prevails as is is said rightly in one of the previous posts is growth, EY will not be able to sustain the projected growth without DEC's etc... this compounded with the culture that has set in will be most difficult to manage, forget factors like whether some will adapt or not.
Now IMHO, RS and CC should be able to circumvent these problems with clear vision and foresight, they will need however the mandate specified and intervention as it seems to happen these days will only make the matters worse.
