Recently I was asked the difference between iteration and disruption in the creative process and after thinking about it for some time in some detail I came to the conclusion that the difference is subtle and has to do with where you look for the answers.
Iterative process comes from asking questions of the typical sources and integrating the answers that you find. Disruptive process comes from asking questions from unexpected sources and integrating the answers that you find.
The subtle difference lies in whether or not you are willing to listen to the answers from an unexpected, and sometimes un-knowledgeable, source. Too many people refuse to listen and this can be their downfall.
Not only will you listen, but do you have the courage to act on it. Courage is seen in many places and one of these places is in the ability to go against the status quo and try something different.
So, if you want to know the difference between an iterative and a disruptive process, look to the least expected source and act upon what you see. This will give you the insight into how you can affect change.
