It works because for more than 46 years, the steps leading up to it have each worked. It rests on solid ground.

Because of the lineage of its model  (for details see reference A)

Because of how well its founder’s model worked  (for details see reference B)

Because it re-invents the concept and the reality of business and personal meetings--these new meetings are an art form, these meetings are a team sport that everyone wins

Because of what the original model and each successive transformation has given participants and those they serve

Because of the enduring wisdom, understanding, good judgment of the principles, environment, methods of the model
               
Because the people who make it work are its clients, those who use it, alone and in groups, because the discipline is self-discipline, because the model is humility

Because the why and the how and the alter egos and the client and client teams and the training and doing and each of the differing and opposing viewpoints are all tightly woven together.
