Innovation is a term that is overused but not very well understood. In my opinion, you can neither do innovation nor be innovative. But there might be some behavioral patterns that foster innovative products. Yet, these pattern need to be discovered.

On this page I would like to collect a few resources, that shed light into the ideas of innovation.
