Three more Zynga's key executives have left the company as part of an ongoing management shake-up at the beleaguered social games developer.
Chief operating officer David Ko, chief people officer Colleen McCreary and chief technology officer Cadir Lee are all stepping down from their positions and leaving the company.
The changes come as the result of a restructuring process led by new CEO Don Mattrick, who left Microsoft for Zynga in July.
In an email sent to Zynga staff (also posted on Zynga's official blog), Mattrick said: "We are taking layers out of the executive rank to get senior leaders closer to important product initiatives."
After announcing the three departures, Mattrick concludes the letter: "With the above in place, I believe that we will have the best chance to grow, build a world class executive team and culture, establish cadence and really become committed to important priorities and opportunities for our long term success."
Last weekZynga shut down OMGPOP, the Draw Something developer Zynga had bought for $180 million in March 2012.
In late July, Zynga's financial results revealed that it had lost over half of its daily active users in a year, going from 72 million daily users in Q2 2012 to 39 million in Q2 2013.
