In this first scheme (left), I like the way it reminds you that “Open” is not only about software, source code. But now that more and more people are aware of the benefits of Open Source software, it’s interesting to also stress the other sides of openness: open standards (like OpenDocument), open hardware, open architecture.
In the second scheme (below) is about the trend from private control / closed access to public control / open access (apparently from Rebecca Henderson; it could be interesting to find this whole presentation from 2004).
There is a third scheme in Avi’s post but there is something I don’t like in it, although it’s visually appealing. Although I understand that proprietary and open innovations should collaborate for the time being, I think that Open Innovation is the model to follow. Moreover, the “speed-to-market” criteria is, imho, better in the Open Innovation model (but maybe I should see Rebecca Henderson’s presentation).
