He's starting with some big challenges - the company just posted a $1.4bn loss, has possibly stranded a pair of their test pilots in orbit, an airliner that can only be described as "probably OK but we're not totally sure", union unrest over the Charleston factory, and the Secret Service is upset over delays and cost overruns on the next Air Force One 747s.
As they say - the only place he can go from here is up.
Just look at Intel.

I've heard of a few more companies who are bleeding engineers and selling off parts to fill the deficit but still keep the divident payouts and stock buybacks rolling as that's the most important of all.
