Microsoft's desperate shuffling of VPs in the wake of the increasing Vista slippage is discussed in depressing depth at MiniMsft. If I were Google, I would do a graduate seminar for executives based on that blog, because it's the ghost of Christmas future that they want to avoid: fiefdoms, sloth, bickering, bureaucracy and low morale.
It reminds me of a handy job survival rule:
When you spend more than 50% of your time complaining or listening to others complain about your place of work, it's time to leave.
