"I used to believe that you could change the culture or behavior of a company. I still believe it's possible, but it is at least a five to ten year process, if you are successful at all. More recently, I have been attracted to the ideas of the behavioralist, Edgar Schein. Schein has argued that you cannot change the culture of a company, but you can use the culture of a company to create change. It's an interesting approach to overcoming resistance. And if you can change how a company does its work, you might eventually be able to change how its people think."
