Citigroup is planning to change its bonus system for senior managers to encourage different parts of the vast company to cooperate and help one another win business, a person familiar with the matter told Reuters.

The change could be difficult to execute, because measuring cooperation can be difficult, experts said. But giving managers incentives to work together fits in with Chief Executive Vikram Pandit's broader strategy of turning around Citigroup by breaking down the divisions between different parts of the bank, instead of breaking apart the financial conglomerate.
