When Yahoo! boss Jerry Yang returned to run the company he founded, he announced a 100-day effort to get the struggling internet giant back on track. So far, the results have been mixed, and today the company's senior executives will meet to discuss ways to streamline the entertainment division and better align the company's other units, according to a MarketWatch report.

"Jerry Yang and Sue Decker are very focused on motivating and aligning key leaders throughout the company to achieve a clear set of goals, and tomorrow's senior management meeting will be an important step in that direction," spokeswoman Kelly Delaney told MarketWatch.

Decker, who has been tasked to be Yang's right hand, has so far managed to reshuffle Yahoo's senior management, bidding farewell to Wenda Harris Millard, the company's former head of North American sales. Decker will also lose Gregory Coleman, the company's global sales EVP, who will depart in February, when his responsibilities will be folded in the new Global Partner Solutions division.

While leadership remains uncertain, and Yahoo looks to a possible acquisition target for Microsoft, the company has managed to make two rather big deals in the past few months. Earlier this month, Yahoo acquired email vendor Zimbra for $350 million and BlueLithium for $300 million.
