Kitchin's qualification for running EnronOnline, it should be pointed out, was not that she was good at it. It was that she wanted to do it, and Enron was a place where stars did whatever they wanted.
EnronOnline was one of the most successful units of Enron. In fact, UBS picked up the platform and now many of the techniques developed at EnronOnline was picked up by the electronic energy trading platforms.
Kitchin is still considered one of the foremost authorities in the world of energy trading and finance. I believe she is a MD at Deutsche Bank in the field of energy structuring and got her development of the business turned into a Harvard Business School case study.
Clearly not only was she good at organizing the business, she succeeded at it. This is exactly what I really dislike about reading Gladwell's stuff. His job is to find a previously successful story-line that has hit snags, in order to act as an armchair quarterback. He is just like most other journalist and historian - seemingly wise because of post-hoc analysis but incapable of actual prediction.
