Well, who is making decisions and how are they being made. What metrics matter? How can we judge them better? How can we improve them in people?

Or, to go even further, have you ever seen Star Trek where they use the holodeck for Training? They have many real-world scenarios so that they can build experience. Couldn't the same be done in many other domains.
