Government-appointed Whitacre wants his managers to:

• Boost U.S. market share north of 20% in 2010, though some analysts expect it to slide from 19.4% now to 15% over the next couple of years

• Bring cars to market much faster, though GM currently matches its peers

• Stop griping about slow decision-making and help change the culture themselves
