Nearly all of my efforts for leading change are focused on building people's capacity to do it themselves. That way you build sustainability into whatever endeavour is being undertaken. The Art of Hosting's work in the European Commission is a brilliant example of this with over 1000 people trained and working for change through applying participatory leadership methods and worldview. In Nova Scotia, where I live, we have trained large numbers of pactitioners as well and incredible work is happening in all sectors from civic engagement and organizational development to local food systems and youth violence. I have heard my friend and mentor, Toke Moeller, say a hundred times (at least) "we build capacity, to build capacity, to build capacity", that is how the momentum of change happens. The building of capacity embeds a relational worldview and set of practices that equip people to build their own path as they walk it - whether that be personal, organizational or in community.
However, a recent blog post by Alan Moore reminded me of the power of strategic intervention to embed change over the long term. Alan referenced an incredible project I was involved in to transform the Nova Scotia Public Health System.
