You and your family are boarding an airplane, and are about to fly across country. How would you want that pilot to have learned how to fly? P.S. It is stormy.
Your daughter is going in for an operation. How would you want that doctor to have learned how to operate?
You are the defendent a big intellectual property lawsuit. How do you want your lawyer to have learned her craft?
Now, is it fair or unfair to talk about project management, leadership, relationship management, and innovation (or other big skills) using those same standards? Is it as important for your boss, or your CEO, or your employee to have the same level of mastery? Is it even possible?
