How to get things done

Today I stumbled upon an article on Steven Sinofsky, the man that is turning Microsoft upside down (in a good way). I particularly enjoyed this part:

"...So Sinofsky told them how he does things. Plan first, then build. Eliminate most middle management. Deliver exactly what you promise, exactly on time"

Makes sense, right? Then why is it so hard for most corporations to grasp this concept?

You can read the whole article here if you want.
