David Cooperrider, developer of Appreciative Inquiry was the guest speaker in our Organizational Leadership class this weekend. Really interesting. Especially that it really grew out of being aware of what was happening in a field experience. In other words, he didn't go out and develop it. He saw something happening and had the sense to see that it was different and to think about it, then go with it. And then it began to fit with theory, and more theory developed, and mechanisms were developed, tested and improved. And now it's a VERY different approach to large-scale change in organizations.
