"Directors are not the problem. Senior execs are."
That's an inaccurate blanket statement.
Plenty of Directors at Dell, who make very bad decisions and no signs of correcting that or taking accountability for their poor decision making.
As another poster mentioned, moving them around is one thing that happens and it doesn't resolve the issue. Not saying there aren't any problems in any other departments...I simply know very well how many Directors operate. And some of their behaviors are a bit shocking. People need to take accountability for their bad decision making and stop repeating those mistakes. That's how good humans operate.
