The greatest obstacles in my mind are our own mental models, the unquestioned assumptions, the stereotypes and beliefs that we individually and as organizations, have. They don't have to be explicit, they don't have to be written down but they are there nevertheless. They are like our genes, they control our behavior and we don't even know that they do so. Every organization has a lot of sacred cows which they are unwilling to bring to the surface and question. And these sacred cows condition what an organization does, what the people in the organization do. The first thing we need to do is to question these sacred cows. These sacred cows have to be brought out, questioned and sacrificed before anybody can come up with any new ideas
