UBS boss hires old friend for senior role

When one reads that the recently appointed CEO of UBS hires a former colleague from his days at Merrill Lynch as Co-Head of Global Investment Banking one has to assume that the hiring old an (business) friend may give a certain amount of comfort and hope that relationships in the top management team will work smoothly. But there is always the danger that sentimental aspects cloud the judgement or that conflicts of interest impede rational decision making or sour the morale of the other team members. The big question is also why a global (?) player like UBS cannot grow its own senior managers. Once you had to be an officer in the Swiss Army to climb the management ladder at the old UBS (before it was taken over by local rival Swiss Bank Corporation) and that surely was not providing an adaequate talent pool (and led to the sorry demise of the 'old' UBS) but has the bank really drawn the right conclusion and found the right formula? The track record over the past 10 plus years speaks a clear verdict.
