For a large European collaboration and research project, OpeningUp, I gave today a lecture about Leadership of Social Sourcing. A lot of the insights at this presentation I have already shared with you on Slideshare or in this weblog. I have added some new and probably inspiring insights about the combination of Groundswell with Spiral Dynamics. And furthermore some and insights on Lean Leadership with Lean problem analyzing and solving principles combined with Social Media data analytics are added to this presentation.
